The invention discloses tendon fixation devices, it includes upper body and lower body, the upper body is inserted into lower body, at least one inserted sheet is provided in the upper body, the straight slot to match with inserted sheet is provided in the lower body, the region for gripping tendon is formed when the inserted sheet is inserted into straight slot, between the lower surface of upper body and the upper surface of lower body.The present invention makes to form certain area between upper body and lower body by the way that inserted sheet to be inserted into straight slot, it would be desirable to which the tendon of clamping is fixed in the region, it is not easy to slip and easy to operate.
Description
Technical field
The invention belongs to medical apparatus and instruments technical fields, and in particular to tendon fixation device.
Background technology
In medical surgery, it is related to the reconstruction of tendon and ligament more, and when tendon and ligament reconstructive, it needs to be derived from body or allosome
Tendon is modified and is sutured, this process must during surgery be carried out using tendon workbench.
However, used tendon fixator on existing tendon workbench, is being tightened for screw nut structure,
In the course of surgery, inconvenient when operating cost, and its generally vertical clamping, cause open section not clamping, is easy during surgery
It slips.
Invention content
The object of the present invention is to provide tendon fixation devices, and solving existing tendon clamp-on holder by parallel clamping holds
Eely problem.
The technical solution adopted in the present invention is tendon fixation device comprising upper body and lower body, it is described upper
Body is inserted into lower body, and at least one inserted sheet is provided in the upper body, is provided in the lower body and matches with inserted sheet
Straight slot, when the inserted sheet be inserted into straight slot in when, between the lower surface of upper body and the upper surface of lower body formed for being clamped
The region of fixed tendon.
The features of the present invention also characterized in that
Further include the self-locking mechanism being arranged inside lower body, the upper body and lower body are fixed by self-locking mechanism.
The self-locking mechanism includes the fixing piece of door character type, the first tooth engaged, shrapnel and spring, first tooth engaged
It is arranged on two vertical edges of fixing piece, the shrapnel is fixed on fixing piece, and the spring setting is used in straight slot bottom
Inserted sheet is popped up.
The second tooth engaged is provided on the inserted sheet.
First tooth engaged and the second tooth engaged are commutating tooth and anti-tooth respectively.
One end of the upper body is clamping face, and the other end in upper body is arranged in the inserted sheet.
One end of the lower body is clamping face, and the other end in lower body is arranged in the straight slot.
Compared with prior art, in use, by the way that inserted sheet to be inserted into straight slot, make to form one between upper body and lower body
Determine region, it would be desirable to which the tendon of clamping is fixed in the region, it is not easy to slip and easy to operate.
Description of the drawings
Fig. 1 is the structural schematic diagram that the embodiment of the present invention provides tendon fixation device；
Fig. 2 is the front view that the embodiment of the present invention provides tendon fixation device；
Fig. 3 is the sectional view in the directions Figure 1A-A；
Fig. 4 is the usage state diagram that the embodiment of the present invention provides tendon fixation device.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention provides tendon fixation device, as shown in Figs 1-4 comprising upper body 1 and lower body 2, on
Ontology 1 is inserted into lower body 2, and at least one inserted sheet 11 is provided in upper body 1, is provided in lower body 2 and 11 phase of inserted sheet
The straight slot 21 matched, in this way, when inserted sheet 11 is inserted into straight slot 21, shape between the lower surface and the upper surface of lower body 2 of upper body 1
At the region for gripping tendon.
Further include the self-locking mechanism 3 being arranged inside lower body 2, in this way, upper body 1 and lower body 2 pass through self-locking mechanism 3
It is fixed, facilitate unlatching and closure.
Self-locking mechanism 3 includes fixing piece 31, the first tooth engaged 32, shrapnel 33 and the spring 34 of door character type, the first occlusion
Tooth 32 is arranged on two vertical edges of fixing piece 31, and shrapnel 33 is fixed on fixing piece 31, and spring 34 is arranged at 21 bottom of straight slot
Portion is provided with the second tooth engaged 12, the first tooth engaged 32 and the second tooth engaged 12 difference for popping up inserted sheet 11 on inserted sheet 11
It is commutating tooth and anti-tooth, in this way, when inserted sheet 11 is inserted into straight slot 21, the first tooth engaged 32 and the engagement of the second tooth engaged 12 make
Certain area is formed between ontology 1 and lower body 2, for fixing tendon；After pressing shrapnel 33, the first tooth engaged 32 and second
Tooth engaged 12 separates, and the spring 34 in 21 bottom of straight slot is arranged and pops up inserted sheet 11.
One end of upper body 1 is clamping face, and the other end in upper body 1 is arranged in inserted sheet 11, and one end of lower body 2 is clamping
The other end in lower body 2 is arranged in face, straight slot 21, in this way, fixing tendon by the clamping face of upper body 1 and lower body 2, does not allow
It easily slips, keeps the cooperation between upper body 1, lower body 2 and tendon even closer.
The course of work：Inserted sheet 11 is inserted into logical by the one end that fixed tendon will be needed to be placed on 2 clamping face of lower body first
In slot 21, upper body 1 moves down at this time, is moved to the first tooth engaged 32 and the engagement of the second tooth engaged 12 after suitable position, upper body 1
It is fixed with lower body 2, finishing operation is carried out to tendon at this time；After operation, after pressing shrapnel 33, the first tooth engaged 32 and
Two tooth engageds 12 separate, and the spring 34 in 21 bottom of straight slot is arranged and pops up inserted sheet 11.
Compared with prior art, in use, by the way that inserted sheet to be inserted into straight slot, make to form one between upper body and lower body
Determine region, it would be desirable to which the tendon of clamping is fixed in the region, it is not easy to slip and easy to operate.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
Subject to.
