Description

A kind of surgical operation fixture

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of surgical operation fixture.

Background technology

In the time performing an operation, need to be by surgery tractor by operative incision to both sides tractive, be convenient to operation technique to expose surgical field of view.Sometimes,, in order to expand surgical field of view, need the hand-held multiple drag hooks of several medical personnel to perform the operation to different directions tractive, medical worker is easy to fatigue with pulling for a long time, not only lavish labor on, and make troubles to operation technique, also easily bring larger misery to patient.Some surgery tractors are invented for addressing the above problem people, for example application number is 201220144455.7, and the utility model that name is called " adjustable retractor for operation " provides a kind of adjustable retractor for operation, comprises bracing frame and drag hook, bracing frame is circular, 90 ° each other of four, its edge screwed holes.Symmetrical grade divided setting; Drag hook is made up of torque arm and coupler body, and the coupler body that can contract the second month in a season is arranged on the top of torque arm, and torque arm body is that the screwed hole of helicitic texture and bracing frame forms screw thread pair, can secondary contract by rotation.When use, be that the sky of each drag hook of capable of regulating is asked distance by rotating and drawing the torque arm of secondary drag hook and coupler body, the support that adapts to scalpel edge is fixed.Drag hook and bracing frame and coupler body adopt adjustable connected mode, have realized drag hook and have asked the adjustable of distance, can make operating theater instruments adapt to wound, are convenient to normally carrying out of operation, have reduced patient's misery.This utility model is simple in structure, easy to use, and processing ease can a people complete operation, especially for the thicker patient of stomach wall, time saving and energy saving, can be widely used in body surface, mammary gland, abdominal operation.For another example application number is: the utility model patent that 200920226247.X name is called " with the operation drag hook for abdomen of drag hook shelf " discloses a kind of operation drag hook for abdomen with drag hook shelf, formed by fixed mount drag hook and drag hook handle, fixed mount is fixed on operating-table, the fixing upper drag hook handle in rear end of drag hook is fixed drag hook retainer ring in the upper end of fixed mount, in the horizontal direction of drag hook retainer ring, establish tapped through hole, in tapped through hole, be provided with threaded rod, fix crank in threaded rod outer end and fix drag hook handle by connector in the inner of threaded rod.This operation drag hook for abdomen with drag hook shelf, compared with the surgery tractor of current use, easy to use, in the time doing abdominal operation, no matter otch is longitudinal, horizontal or oblique, all can be to both sides tractive operative incision, and tractive scope is wide, visual area is large, the labor intensity that has reduced staff, facilitates operation technique, has improved operation efficiency.Again for example, application number is: 201320161400.1 are called: the utility model of " a kind of laparoscopic surgery retractor " provides a kind of laparoscopic surgery retractor, comprise the circular arc body with cavity that some joints are flexibly connected, the radial cross-section of circular arc body is C type, in circular arc body, be provided with several cylindrical traction slide blocks, the diameter of traction slide block disc is less than the diameter of circular arc body cavity, traction slide block comprises the housing with outlet, in housing, be provided with rotating shaft and connecting band, in rotating shaft, be provided with the wind spring being connected with housing, one end of connecting band is wrapped in rotating shaft, the other end of connecting band passes the outlet of housing and is connected with L-type drag hook.The beneficial effects of the utility model are: in operation process, do not need artificial tractive, reduced labor intensity, tractive dynamics is even, easy to use.

For first patent application, adopt fixed mount, multiple drag hooks are fixed on fixed mount, and do not need artificial tractive, the labor intensity that has reduced medical personnel, facilitates operation technique, has improved operation efficiency, but the position of drag hook is fixed, the direction of pulling force is non-adjustable.Although the orientation of second patent application drag hook is adjustable, and the pull bar length of drag hook is adjustable, and the orientation of transferring is only confined to several positions, and the position that the 3rd patent application realized drag hook is adjustable continuously, but structure is very complicated, and cost cost is higher.

Summary of the invention

It is adjustable that the technical problems to be solved in the utility model is to provide a kind of pull bar length of drag hook, and the position of drag hook is adjustable continuously, and structure is very simple, the surgical operation fixture that cost cost is low.

For solving the problems of the technologies described above, this utility model is to be achieved through the following technical solutions: a kind of surgical operation fixture, comprise clamping rings, torque arm, drag hook, on described clamping rings, be set with slide block, on slide block, be provided with fixed screw, described torque arm one end is fixedly installed joint sleeve, and the other end is fixedly connected with slide block, on the pull bar of described drag hook, screw thread is set, pull bar is connected with described torque arm by adjusting nut through after joint sleeve.

Described slide block, torque arm, drag hook are as a whole, and overall quantity is 4-6.

Described clamping rings lower end is fixedly connected with four poles, the lower end fixed installation sucker of described each pole.

Universal rotating shaft is set on described clamping rings, in universal rotating shaft, is fixedly installed a magnifier.

The beneficial effects of the utility model are: 1, the position of drag hook is adjustable continuously, simple in structure, cost cost is low: this utility model by being set with multiple slide blocks with fixed screw on clamping rings, sliding slider can be transferred to drag hook arbitrary position, then fixed screw is tightened slide block is fixed, thereby realized the adjustable continuously of drag hook position, structure is also fairly simple.2, convenient fixing: be fixedly connected with four poles in clamping rings lower end, the lower end fixed installation sucker of each pole, thus sucker can be adsorbed on patient skin and easily surgical operation fixture is fixed on patient body.3, there is amplification: by a magnifier is set on clamping rings, if operative site is very little, can utilize magnifier clearly to see the tissue of operative site clearly.
