Abstract

An external fixer for hand operation belongs to surgical instrument field and comprises a bottom plate and a hook, which is characterized in that a moundy protrusion is arranged on and higher than the bottom plate, and the hook is uniformly distributed on the edge of the bottom plate, wherein, a concave groove is arranged between two adjacent hooks. The utility model can effectively prevent movement of hand and finger during operation which influences operation, and expose operation field sufficiently; the utility model has small volume, simple operation, low manufacture cost, firmness, durability and ideal fixing effect; both sides of the utility model can be used to adapt to different operation requirements; the rinsing liquid and wound blood in operation treatment can be discharged automatically, which is beneficial for the normal and continuous operation. The utility model is mainly applied to hand operations, such as replantation of severed finger, half-palm or full-palm disarticulation repair, thumb reconstruction, tendon reconstruction and so on, and is also applied to tenosynovitis and ganglion operation, hand scar excision, skin grafting or flap transfer operation.

Description

Hand operation external fixer

Technical field this utility model belongs to the surgical instruments field, relates in particular to the medical equipment that a kind of hand operation is used.

Background technology is being carried out palm, the back of the hand or finger position in surgical operation or the debridement process at present, the hand that needs assistant's support, immobilized patients specially, to keep the operation location of patient's hand operation, so the assistant has just occupied quite a few operative space, has influenced the operation of operator to a certain extent.In addition, when carrying out the hand microsurgery, because operating time is longer, the assistant is easily producing fatigue in the support process for a long time, the accurate location of hands or finger and not being moved in can't guaranteeing to perform the operation, thus it is clear to have influenced abundant exposure and the imaging of operative site in field of microscope.

Chinese patent ZL 97205817.6 discloses a kind of " a kind of hand operation is many with dish ", and this dish has an approximate rectangular plate, and three webs on this dish are provided with uniform substantially hook, have an arc port on the another side, and trying to get to the heart of a matter is a plane.Can clean wound in the dish, the plane of trying to get to the heart of a matter cooperates the hook of web, can assist with elasticity lines adversary fingering row again and fix, and severed finger (hands) is replanted and other hand operations to carry out.Because this tray bottom is the plane, does not meet the anatomical structure feature of hand under the natural relaxation state, and operative site is exposed fully, make troubles for the operation of patient and operator; Simultaneously, liquid that washes in the surgical procedure and wound crimson blood also accumulate in this tray bottom and can't discharge voluntarily, flow out, and influence normally carrying out continuously of operation technique.

Summary of the invention goal of the invention of the present utility model provides the hand operation external fixer that the liquid that washes in a kind of abundant exposure of being convenient to operative site, the surgical procedure and wound crimson blood can discharge voluntarily.

The technical solution of the utility model provides a kind of hand operation external fixer, comprises base plate and bent hook, it is characterized in that the mound shape projection that is higher than base plate plane is set on described base plate, and bent hook is distributed in the edge of base plate, between the two adjacent bent hooks recessed groove is set.

The bending curve of wherein said mound shape projection and the bending curve of human hands under the natural relaxation state coincide; Top in described mound shape projection is provided with outage; Described bent hook is distributed in two opposed edges of base plate.

Compare with background technology, the utility model has the advantages that:

1. can effectively prevent to occur the mobile of hands, finger in the art and influence operation technique, and fully expose surgical field of view.

2. liquid that washes in the surgical procedure and wound crimson blood can discharge voluntarily, help normally carrying out continuously of operation technique.

3. two-sidedly all can use, to adapt to different operation needs.

4. volume is little, and operation is simple, and the fixed effect ideal is beneficial to the carrying out of operation.

Description of drawings Fig. 1 is the structural representation of an embodiment of this utility model; Fig. 2 is that the A of Fig. 1 is to view; Fig. 3 is that the B of Fig. 1 is to view; Fig. 4 is that the C-C ' of Fig. 1 is to cutaway view.

In Fig. 1～Fig. 4, two opposed edges of base plate 1 are evenly equipped with between 2, two adjacent bent hooks of bandy bent hook recessed groove 5 are set, and the mound shape projection 3 that is higher than base plate plane is set on the base plate, and the top of mound shape projection is provided with outage 4.

The bending direction of bent hook outwards be, also but lateral thrust or be other form of being convenient to operate, the body shape of bent hook can also can be taked the form of other form such as zona columnaris crotch etc. as described in the accompanying drawing.

Specific embodiment this utility model when reality is used, with elasticity lines such as rubber bar or gauzes by the bent hook in both sides or recessed groove fixedly palm, finger.These external fixer tow sides all can use, to adapt to different operation needs.When shape protruding part, mound upwards when just putting (be external fixer),, the back of the hand is fully exposed if upwards place in the hand centre of the palm; If place in the hand centre of the palm, facies palmaris is fully exposed downwards.When shape protruding part, mound downwards when being inverted (be external fixer),, can make flexor of the hand, flexor tendon lax if the hand centre of the palm upwards places; If place downwards in the hand centre of the palm, then can make the back of the hand portion extensor tendon lax, be convenient to operation technique.

When this utility model is just being put use, liquid that washes in the surgical procedure and wound crimson blood can be discharged voluntarily by two edges of not establishing bent hook on the base plate, when this utility model is inverted use, liquid that washes in the surgical procedure and wound crimson blood can be discharged by the outage that is arranged on the shape protruding part, mound, have guaranteed normally carrying out continuously of operation technique.

This utility model can adopt metal or thermostability engineering plastic material, and cost of manufacture is low, and is sturdy and durable, available medicining liquid dipping sterilization, also available high-temperature high-voltage sterilizing sterilizing.

This utility model is applicable to that mainly replantation of amputated finger, half palm or the full palm from the operation of hands such as disconnected reparation, thumb reconstruction, tendon reconstruction, also can be used for tenosynovitis, thecal cyst operation and operations such as hand scar excision, skin-grafting or transfer of skin flap.
