Description
Technical field
This utility model relates to medical instruments field, relates to more specifically a kind of mandible angle retractor.
Background technology
Surgical operation often will be used drag hook (having another name called hook or retractor), mainly due to pulling open to make internal organizational structure to reveal epidermis etc. in operation, is the indispensable apparatus in surgical operation.
In the time carrying out the operation of intra-oral approach angle of mandible; in operation process, need to press close to mandibular bone lateral surface to grind bone and cutting operation; because the lacuna of angle of mandible position is narrower and small; and in the soft tissue of outside, be distributed with important blood vessels and very easily sustain damage, therefore need to use mandible angle retractor to protect soft tissue and blood vessel.The end of mandible angle retractor of the prior art mostly is circular-arc, less with outside soft tissue contact portion, and cannot area larger props up soft tissue to come, and can not effectively protect soft tissue and blood vessel.
Therefore, need a kind of mandible angle retractor that can effectively protect soft tissue and blood vessel in operation badly, can better be protected in operation process so that obtain patient.
Utility model content
The purpose of this utility model is, proposes a kind of mandible angle retractor, can in operation process, protect patient's outside soft tissue and blood vessel, the possibility coming to harm in operation process to reduce patient.
For reaching this object, this utility model by the following technical solutions:
A kind of mandible angle retractor, comprises handle, and one end of described handle is connected with drag hook, and described drag hook is in T shape.
Further, described drag hook comprises orthogonal First and second, and one end of described First is connected with the centre of described second; The other end of described First is connected with described handle first end; Between described First and described handle, be 90 ° ± 5 ° angles.
Further, the second end of described handle has draw ring.
Further, offer loss of weight ring on described handle, described loss of weight ring is cirque structure; Described loss of weight ring one end is connected with the second end of described handle, and the other end of described loss of weight ring is connected with described draw ring.
Preferably, the length of described handle is 24 ± 0.1cm.
Preferably, the length of described drag hook is 8 ± 0.1cm.
Further, the length of described drag hook is 5 ± 0.1cm.
Further, the width of the First of described drag hook is 1 ± 0.1cm; The width of described handle is less than the width of described First.
Preferably, the length of described second is 3 ± 0.1cm; The width of described second is 1 ± 0.1cm.
Preferably, described handle and the drag hook structure that is formed in one, described handle and drag hook are made up of stainless steel.
Preferably, described stainless steel is 20Cr13 or 6Cr19Ni10.
The beneficial effects of the utility model are:
(1) mandible angle retractor in this utility model, the end of drag hook is T font, circular-arc end compared to existing technology, this utility model is in use larger with the contact area of soft tissue, increase the protected area to soft tissue in operation lacuna, reduce the probability that in operation process, electric drill contacts with soft tissue, prevented that soft tissue is hemorrhage because of damage, made operation process safer, reliable;
(2) in this utility model, the one end at handle is provided with draw ring, and the convenient control to drag hook only needs to use finger drag hook can be close on soft tissue, and use procedure is more laborsaving;
(3) on the handle in this utility model, be provided with loss of weight ring, the setting of loss of weight ring makes the deadweight of mandible angle retractor lighter, indefatigability in use procedure.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment mono-
As shown in Figure 1, be a kind of mandible angle retractor that the present embodiment proposes, comprise handle 1, one end of described handle 1 is connected with drag hook 2, and described drag hook 2 is in T shape.The drag hook 2 of T font comprises orthogonal First 21 and second 22, and one end of described First 21 is connected with the centre of described second 22; The other end of described First 21 is connected with the first end of described handle 1; Between described First 21 and described handle 1, be 90 ° ± 5 ° angles.
The length of handle 1 described in the present embodiment is 24 ± 0.1cm, and the length of described drag hook 2 is 5 ± 0.1cm, and the length of drag hook 2 described herein is First 21 and second 22 length altogether.The width of the First 21 of described drag hook 2 is 1 ± 0.1cm; The width of described handle 1 is less than the width of described First 21.
The length of second 22 of described drag hook 2 is 3 ± 0.1cm; The length of second 22 described herein is the length of the horizontal end of " T " font, and the width of described second 22 is 1 ± 0.1cm, and the width of described second 22 is the width of the horizontal end of " T " font.In the present embodiment, the end of drag hook 2 is T font; circular-arc end compared to existing technology; mandible angle retractor in the present embodiment is in use larger with the contact area of soft tissue; increase the protected area to soft tissue in operation lacuna; reduce the probability that in operation process, electric drill contacts with soft tissue; prevent that soft tissue is hemorrhage because of damage, make operation process safer, reliable.
