Abstract

Claims (12)

1 . A head brace with an adjustable-length connector, comprising:

a connector comprising an outer cover body, an inner core body, a reversible structure, and a fixation rope body, wherein said outer cover body is suitable for being sleeved on the outer end of said inner core body, wherein said reversible structure is installed on said inner core body, wherein said fixation rope body is suitable for being connected to said outer cover body and said inner core body, so as to tighten said fixation rope body by the forward rotation of said inner core body relative to said outer cover body, and to relax said fixation rope body by a reverse rotation of said inner core body relative to said outer cover body through said reversible structure, so as to realize the adjustable length of said fixation rope body of said connector; and

a head brace comprising a guidance adapter and a head clamp, wherein said guidance adapter is suitable for being installed on said head clamp, wherein said connector is suitable for being installed on said head clamp through said guidance adapter:

wherein said inner core body comprises a fixation member and a grip member, wherein said fixation member is integrally connected to said grip member;

wherein said outer cover body has an inner core accommodation cavity, wherein said fixation member of said inner core body is suitable for being accommodated in said outer cover body through said inner core accommodation cavity of said outer cover body:

wherein said outer cover body has a first fixation hole, a second fixation hole, and a third fixation hole, wherein said first fixation hole, said second fixation hole, wherein said third fixation hole are located on the side end of said outer cover body, wherein said first fixation hole and said second fixation hole are on one side of said outer cover body, wherein said third fixation hole is on the other side of said outer cover body, wherein said first fixation hole and said third fixation hole are on the same axis.

2 . The head brace, as recited in claim 1 , wherein said fixation member has a first fixation groove and a second fixation groove, wherein said first fixation groove and said second fixation groove are located on the side end of said fixation member, recessed on the surface of the side end of said fixation member, wherein said fixation member further has a first inner hole and a second inner hole, wherein said first inner hole and said second inner hole are respectively located at the bottom of said first fixation groove and said second fixation groove, and horizontally penetrate said fixation member, wherein said first inner hole is on the same axis as said first fixation hole and said third fixation hole, wherein said second inner hole is on the same axis as said second fixation hole, wherein one end of said fixation rope body is suitable for passing through said first fixation hole, said first inner hole, and said third fixation hole, wherein the other end of said fixation rope body is suitable for passing through said second fixation hole and said second inner hole, so that when said inner core body rotates relative to said outer cover body, the two ends of said fixation rope body are respectively wound around said first fixation groove and said second fixation groove, so that the length of said fixation rope is continuously reduced, thereby fixing the medical device on the outer wall of said outer cover body.

3 . The head brace, as recited in claim 2 , wherein said outer cover body has a clamping groove, which is located on said inner wall of said outer cover body, recessed on said inner wall of said outer cover body and communicating with said inner core accommodation cavity.

4 . The head brace, as recited in claim 3 , wherein said reversible structure comprises a control member and a connection unit, wherein said control member is installed on said grip member, wherein said clamping member is installed on said fixation member, wherein said clamping member is suitable for engaging with said clamping groove of said outer cover body to achieve fixation.

5 . The head brace, as recited in claim 4 , wherein said reversible structure further comprises a connection unit, wherein one end of said connection unit is connected to said clamping member, wherein the other end of said connection unit is connected to said control member, so as to drive the movement of said clamping member through said connection unit connected to said control member by controlling the movement of said control member, so as to realize the engagement and separation of said clamping member and said clamping groove, and thus realize the reversible rotation of said inner core body.

6 . The head brace, as recited in claim 5 , wherein said reversible structure further comprises an elastic element, wherein one end of said elastic element is connected to said clamping member or said connection unit, wherein the other end of said elastic element is connected to said inner core body.

7 . The head brace, as recited in claim 6 , wherein said fixation member further has an installation hole, wherein said clamping member is suitable for being installed on said fixation member through said installation hole.
