Abstract
本实用新型涉及一种软骨修剪专用夹持器。其由手柄和盘状接触面组成，所述手柄通过转轴与盘状接触面连接，所述手柄包括握持部分和簧片，所述握持部分通过转轴调节盘状接触面的间距，所述盘状接触面通过下托盘和上盖板与所修剪的软骨接触。本实用新型的夹持器克服了现有操作稳定性差的问题。术者可以从各个角度进行切削，操作简便，节省时间。
The utility model relates to a special clamper for cartilage trimming. It consists of a handle and a disc-shaped contact surface, the handle is connected to the disc-shaped contact surface through a rotating shaft, the handle includes a holding part and a reed, and the holding part adjusts the distance between the disc-shaped contact surfaces through a rotating shaft. The disc-shaped contact surface is in contact with the trimmed cartilage through the lower tray and upper cover plate. The clamper of the utility model overcomes the problem of poor operation stability in the prior art. The operator can cut from all angles, which is easy to operate and saves time.
Description
Technical field
This utility model relates to the medical surgical operating theater instruments, is specifically related to a kind of clamper.Prune the cartilage that cartilage uses during particularly a kind of ent surgery and prune clamper.
Background technology
Tympanoplasty is effective Therapeutic Method of conductive deafness, is that the tympanum of using always is repaired and the ossicular chain reconstruction biomaterials from the body cartilage.For adapting to individual instances, the cartilage that needs to take from tragus or cavity of auricular concha is pruned, and medical institutions use the dentation tweezers to come the clamping cartilage in operation at present, prune cartilage with knife blade.This mode is difficult to stable hold the cartilage sheet with skiving and moulding.Operation easier is big, and success rate is low.
The utility model content
The problem that the purpose of this utility model exists to existing cartilage cut operation just provides a kind of novel cartilage to prune dedicated workholder, cartilage is fixed in the holder of a disc band pressing plate, has overcome the problem of existing operational stability difference.The patient can cut from all angles, and is easy and simple to handle, saves time.
This utility model is realized through technical scheme once:
A kind of cartilage is pruned dedicated workholder; Form by handle and plate-like contact surface; Said handle is connected with the plate-like contact surface through rotating shaft; Said handle comprises grip portions and reed, and said grip portions is through the spacing of rotation shaft regulated plate-like contact surface, and said plate-like contact surface contacts with the cartilage of being pruned with upper cover plate through following pallet.
Preferably, said plate-like contact surface also comprises pallet and upper cover plate down, guarantees the stability of gripped object.
Preferably, said plate-like contact surface is disc contact surface, shape of a saddle contact surface or bathtub shape contact surface, guarantees that difform tissue all can be cut.
Preferably, said handle comprises rotating shaft and preceding curved boom, makes down pallet and upper cover plate keeping parallelism.
Preferably, said handle also comprises position-limiting spring leaf, makes clamper when no external force, be in open mode.
Compare with existing operating process, the utlity model has following advantage:
Through pallet and cover plate design, effectively increased clamping stability, improve success rate;
The position-limiting spring leaf design makes contact surface be in opening, saves operating time.
Pallet and upper cover plate keeping parallelism are down guaranteed in preceding curved boom design, make gripped object stressed evenly, reduce the cartilage injury.
Multiple contact surface design, the difform tissue of convenient cutting.
A kind ofly be used for tympanoplastic cartilage and prune dedicated workholder, it is characterized in that: be made up of handle and plate-like contact surface, said handle is connected with the plate-like contact surface through rotating shaft; Said handle comprises grip portions; Said grip portions is through the spacing of rotation shaft regulated plate-like contact surface, and said plate-like contact surface also comprises pallet and upper cover plate down, and said plate-like contact surface contacts with the cartilage of being pruned with upper cover plate through following pallet; Said handle comprises rotating shaft and preceding curved boom; Make down pallet and upper cover plate keeping parallelism, said handle also comprises position-limiting spring leaf, makes clamper when no external force, be in open mode; Said plate-like contact surface is disc contact surface, shape of a saddle contact surface or bathtub shape contact surface, guarantees that difform tissue all can be cut.
Description of drawings
Fig. 1 prunes the dedicated workholder structural representation for this utility model cartilage.
Fig. 2 prunes the operation principle sketch map of dedicated workholder for this utility model cartilage.
Fig. 3 prunes dedicated workholder work sketch map for this utility model cartilage.
Fig. 4 prunes dedicated workholder (shape of a saddle tissue contact surface) work sketch map for this utility model cartilage.
Fig. 5 prunes dedicated workholder (bathtub shape tissue contact surface) work sketch map for this utility model cartilage.
The specific embodiment
A kind of cartilage shown in Fig. 1-5 is pruned dedicated workholder; Form by handle and plate-like contact surface; Said handle is connected with the plate-like contact surface through rotating shaft; Said handle is made up of: grip portions (3,4), position-limiting spring leaf (5), rotating shaft (6), preceding curved boom (7), and said plate-like contact surface is by following pallet (1) and upper cover plate (2) formation.
The plate-like contact surface comprises pallet (1) and upper cover plate (2) down, guarantees the stability of gripped object.
Handle comprises rotating shaft (6) and preceding curved boom (7), makes down pallet and upper cover plate keeping parallelism.Said handle also comprises position-limiting spring leaf (5), makes clamper when no external force, be in open mode.
Claims (6)
