Abstract

The utility model relates to a medical sagittal 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 spindle is fixedly provided with a waterproof ring and an O-shaped ring; a bearing is positioned by a fix spring to be placed inside the cavity of a fast-changing seat of a rear shell; an eccentric column of the spindle is nested with a wear-resistant sleeve which is fixed by the fix spring to be connected with a driven shaft, one end of which is provided with a sheath fixed on a bracket inside the front cavity of a front shell; and a tool holder of the sagittal saw is inserted into the positioning hole of the driven shaft to be fixed by a check 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 sagittal saw

Technical field

Novel a kind of medical surgical operating theater instruments, the particularly a kind of medical sagittal 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 sagittal 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 water proof ring (2), O type circle (3) and bearing (4) jump ring (5), jump ring (6) location places in quick change seat (8) cavity of rear casing (7), biasing post (9) the suit wear-resistant sleeve (10) of main shaft (1) connects with driven shaft (12) with jump ring (11) is fixing, driven shaft (12) one ends are equipped with sheath (13) and are fixed on the support (16) in the preceding cavity (15) of front casing (14), the locating hole (19) that sagittal saw (17) handle of a knife (18) inserts driven shaft (12) tightens up with lock nut (20), quick change seat (8) shell is equipped with water inlet pipe (21), front casing (14) housing is equipped with outlet pipe (22) outward, is connected by the intravital water cavity of shell (23) between water inlet pipe (21) and the outlet pipe (22).The shape of sagittal saw (17) can be front wide and rear narrow or beloid, can outer male bend or indent curved.

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) installs water proof ring (2), O type circle (3) and bearing (4) jump ring (5), jump ring (6) location places in quick change seat (8) cavity of rear casing (7), biasing post (9) the suit wear-resistant sleeve (10) of main shaft (1) connects with driven shaft (12) with jump ring (11) is fixing, driven shaft (12) one ends are equipped with sheath (13) and are fixed on the support (16) in the preceding cavity (15) of front casing (14), the locating hole (19) that sagittal saw (17) handle of a knife (18) inserts driven shaft (12) tightens up with lock nut (20), quick change seat (8) shell is equipped with water inlet pipe (21), front casing (14) housing is equipped with outlet pipe (22) outward, is connected by the intravital water cavity of shell (23) between water inlet pipe (21) and the outlet pipe (22).Main shaft of the present utility model (1) is fluted along the circumference boring, biasing post (9) installs wear-resistant sleeve (10) and inserts in the groove with jump ring (11) location, having groove with driven shaft (12) one ends connects, guaranteed that biasing post (9) reduces abrasion to driven shaft (12) in working long hours, increase work efficiency.Connect by the intravital water cavity of shell (23) between the water inlet pipe (21) that quick change seat (8) shell is equipped with and the outlet pipe (22) that front casing (14) is equipped with, make water cycle around the drive mechanism of apparatus, form cooling reduction of heat system, the strong guarantee apparatus can use for a long time, reduces the risk that apparatus brings in operation process.The shape of Fig. 2 sagittal saw (17) can be front wide and rear narrow or beloid, can outer male bend or indent curved.Mainly be according to different operative sites area, the degree of depth, carry saw and plug into, and the sagittal saw (17) of location different shape, helping operation carries out smoothly, effectively guarantees the operation quality.
