Abstract

The utility model relates to a medical swinging saw, which solves the problem that the past reciprocating saw can not splice, swing or shape in the complicated and difficult surgical operations. The utility model is characterized in that a bearing is fixedly arranged; the two ends of an O-shaped ring are fixedly connected to a waterproof frame by two fix springs to be placed inside the cavity of a fast-changing body; one end of a driven shaft is nested with a bearing; a wear-resistant sleeve, the fix spring and a spindle are connected and fixed inside the cavity of a front shell; the other end of the driven shaft is fixedly provided with a bearing, a waterproof pad ; a positioning sleeve is fixed at the head end of the front shell by a fix spring; and a rod of a cutter is connected to the positioning sleeve of the driven shaft , and is locked by a lock nut. The utility model has the advantages of reasonable design, scientific structure, small size, light weight, strong heat dissipating capability, small work impact force, low noise, convenient operation, easy repair and low manufacturing cost.

Description

Medical swing saw

Technical field

Novel a kind of medical surgical operating theater instruments, the particularly a kind of medical swing saw that is used for shaping and beauty, Wicresoft's engraving bone surgery of relating to of this usefulness.

Background technology

At present, along with the develop rapidly and the continuous progress in science and technology of economic construction, industry-by-industry is refinement more and more, and the instrument of industry-by-industry is progressively perfect, has more hommization, and reliability is in the hope of reaching optimum efficiency.In the hospital surgery plastic operation, the application of reciprocating sow is very extensive.Plugging into of various traumatic fracture; Shaping jawbone osteotomy is removed art; The operation of pathological changes bone or osteoarthrosis dislocation, displacement all has very high dependency to the reciprocating sow apparatus.This type of operation of past, the reciprocating sow of employing can not be suitable for special wound, have a big risk, anhydrous flushing very easily pollutes, cause the appearance damage, do not satisfy the recessive wound of Wicresoft's shaping, dystopy of the difficult operation of modern surgery and dodge the specification requirement of performing the operation in the soft tissue deep.

Summary of the invention

The purpose of this utility model provides a kind of compact conformation, and is rationally distributed, easy to use, is easy to safeguard, requires to implement the medical swing saw of circuitous goose saw according to the difference of operation different parts.

The purpose of this utility model is achieved through the following channels: main shaft (1) installs bearing (6) and O type circle (24) two ends jump ring (10), jump ring (12) is fixedly linked in waterproof frame (23) and places quick change body (11) intracavity, driven shaft (2) one end bearing sets (7), wear-resistant sleeve (13) and jump ring (14) are connected and fixed in front casing (9) cavity with main shaft, driven shaft (2) other end is fixed with bearing (20), collision mat (16) and positioning sleeve (17) fixedly place front casing (9) head end with jump ring (18), the knife bar (21) of cutter (22) is connected in the positioning sleeve (17) of driven shaft (2) and is locked by lock nut (19), rear casing (3) is equipped with water inlet pipe (4), front casing (9) head end is equipped with outlet pipe (15), has water cavity (5) in the cavity between water inlet pipe (4) and the outlet pipe (15).

The utility model has the advantages that: 1, reasonable in design, simple in structure.Adopt human oriented design, guaranteed the safety of operation, reliable, avoid high-leveled and difficult operation process because the various risks that apparatus brings.2, can be suitable for various surgical plastics, Wicresoft, plug into and the difficult complicated operation of engraving property, improve the operation quality, practical.3, heat-sinking capability is strong, and volume is little, and is in light weight, and high efficiency is easy to maintenance, and is cheap.

Following a tree name accompanying drawing is described in further detail this utility model:

The specific embodiment

As can be seen from Figure 1, this utility model main shaft (1) install bearing (6) and O type circle (24) up and down between with jump ring (10), jump ring (12) is fixedly linked in waterproof frame (23) and places quick change body (11) intracavity, driven shaft (2) one end bearing sets (7), wear-resistant sleeve (13) and jump ring (14) are connected and fixed in front casing (9) cavity with main shaft, driven shaft (2) other end is fixed with bearing (20), collision mat (16) and positioning sleeve (17) fixedly place front casing (9) head end with jump ring (18), the knife bar (21) of cutter (22) is connected in the positioning sleeve (17) of driven shaft (2) and is locked by lock nut (19), rear casing (3) is equipped with water inlet pipe (4), front casing (9) head end is equipped with outlet pipe (15), has water cavity (5) in the cavity between water inlet pipe (4) and the outlet pipe (15).This utility model adopts main shaft (1) and the eccentric draw bail of driven shaft (2), install jump ring (10), jump ring (12), 0 type circle (24) and wear-resistant sleeve (13) in the connection place, reduce the noise that main shaft (1) high speed working in reciprocating mode is brought, alleviate impulsive force, effectively guaranteed the working environment of operation and safe and reliable.Have water cavity (5) in the cavity between rear casing (3) water inlet pipe (4) and front casing (9) outlet pipe (15), form the liquid water circulation system, effectively the operating temperature of control device in operation process finished various differences and complicated surgical operation.
