Description

Bone holding forcep

Technical field

The utility model belongs to the field of medical instrument technology, and in particular to a kind of bone holding forcep.

Background technology

Bone holding forcep supply to clamp bone during bone surgery, play the role of fixed, reset, in than narrow operative space During operation, the hand for holding bone holding forcep easily blocks sight, and doctor, which needs to change position repeatedly, just can be clearly seen that patient's hand Art position, in surgical procedure, so operates the fatigue strength for undoubtedly adding doctor, increases operation risk for a long time, and And the pincers lobed shape of existing bone holding forcep on the market is relatively simple, it is linear contact when clamping the occlusal surface and bone contact of valve, leads Cause holding dynamics it is inadequate, in reseting procedure, reset effect is easy to be lost, need to reset again, extend operating time, increase wound and Pain.

The content of the invention

The purpose of this utility model is to provide one kind not to block sight, clamping part and bone contact face in surgical procedure The big bone holding forcep of product, during operative reduction firm grip, hold great efforts, be not easy to slip, better reduction.

The utility model is realized in this way：A kind of bone holding forcep, including upper tong arm and lower tong arm, it is characterised in that：It is described Upper tong arm and lower tong arm it is hinged, the front end of upper tong arm is lower clamping part, and the clamping face of lower clamping part is cancave cambered surface, under Valve is clamped in the end of clamping part for V-type, and the rear end of upper tong arm is upper grip part, and the front end of lower tong arm is upper clamping part, upper clamping part End clamp valve for cylindrical type, the front end of cylindrical type pincers valve is semi-round ball, and the surface of semi-round ball is zigzag, the rear end of lower tong arm For lower grip part, upper and lower clamping part and tong arm in one plane, clamp are not provided with front of the grip part of upper and lower tong arm The latch and buckle of locking.

The upper tong arm and lower tong arm by pin-hinges into scissor-shaped, using the axial method of clamping for the formula of filling the span of a man's arms.

The V-type pincers valve is V-shaped in vertical plane.

The lower clamping part is micro-bend arc in vertical plane, the folder between the section of arc and upper tong arm plane Angle is 20 ° -30 °, and upper clamping part is identical with the arcuate structure of lower clamping part.

The latch and buckle mutually fasten, and the phase of upper tong arm and lower tong arm is locked by fastening for latch and buckle To position, chucking power is kept.

Compared with prior art, the beneficial effects of the utility model are：The bare terminal end of bone holding forcep is provided with pincers valve, and The semicircle ball surface of pincers valve is provided with jagged anti-slop serrations, and the crown of anti-slop serrations and the blessing area of bone are small, in clamping Pressure is big, can be very good occlusion bone, and valve and bone are clamped in reseting procedure will not occur relative displacement, and it is accurate to reset, V-type The design of pincers valve can increase the contact area with bone, and the design of semi-round ball clamp valve is when pincers valve is contacted with meat tissue, to the greatest extent The possible damage for reducing pincers valve to meat tissue, mitigates the postoperative pain of patient, and the bone holding forcep of the utility model are held at the time of surgery, Angle between the section of the clamping face arc of bone forceps and tong arm plane is 20 ° -30 °, can in than narrow operative space Sight is blocked to avoid the hand for holding pincers, doctor can be clearly seen that corrective surgery in the case where that need not change position Position, the pincers valve of clamping part can come into full contact with bone, and holding dynamics is good, and in reseting procedure, reset effect is not easy to lose.

Brief description of the drawings

Fig. 3 is I enlarged drawing of Fig. 1

In figure：1-V types clamp valve, 2- cylindrical types pincers valve, the upper clamping parts of 3-, clamping part under 4-, 5- pins, the upper tong arms of 6-, 7- Lower tong arm, 8- are buckled, 9- latches, the upper grip parts of 10-, grip part under 11-.

Embodiment

Embodiment 1, as shown in Fig. 1 to 3 structures, a kind of bone holding forcep, including upper tong arm and lower tong arm, it is characterised in that：Institute The upper tong arm 6 and lower tong arm 7 stated are hinged to scissor-shaped by pin 5, using the axial method of clamping for the formula of filling the span of a man's arms, upper tong arm 6 Front end is lower clamping part 4, and the clamping face of lower clamping part 4 is cancave cambered surface, and valve 1, V-type pincers valve 1 are clamped in the end of lower clamping part 4 for V-type V-shaped in vertical plane, the rear end of upper tong arm 6 is upper grip part 10, and the front end of lower tong arm 7 is upper clamping part 3, upper clamping part 3 End for cylindrical type clamp valve 2, cylindrical type pincers valve 2 front end be semi-round ball, the surface of semi-round ball is zigzag, lower tong arm 7 Rear end is lower grip part 11, and not in one plane, lower clamping part 4 is in vertical plane to be micro-bend for upper and lower clamping part and tong arm Arc, the angle between 6 plane of the section of arc and upper tong arm is 20 ° -30 °, the arc of upper clamping part 3 and lower clamping part 4 Structure is identical, and the latch 9 and buckle 8 of clamp locking are provided with front of the grip part of upper and lower tong arm, and latch 9 and buckle 8 are mutual Fasten, the relative position of upper tong arm and lower tong arm is locked by the fastening of latch 9 and buckle 8, keeps chucking power.

When the utility model is used, the bare terminal end in bone holding forcep is provided with pincers valve, and set in the semicircle ball surface of pincers valve Jagged anti-slop serrations are equipped with, the crown of anti-slop serrations and the blessing area of bone are small, and pressure is big in clamping, can be very good to sting Bone is closed, valve and bone are clamped in reseting procedure will not occur relative displacement, and it is accurate to reset, and the design of V-type pincers valve can increase With the contact area of bone, the design of semi-round ball clamp valve reduces pincers valve to meat as far as possible when pincers valve is contacted with meat tissue The damage of tissue, mitigates the postoperative pain of patient, the bone holding forcep of the utility model clamping face arc of bone holding forcep at the time of surgery, Angle between section and tong arm plane is 20 ° -30 °, can be hidden in than narrow operative space to avoid the hand for holding pincers Sight is kept off, doctor can be clearly seen that corrective surgery position, the pincers valve of clamping part in the case where that need not change position It can be come into full contact with bone, holding dynamics is good, and in reseting procedure, reset effect is not easy to lose.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this area Technical staff for, various modifications and changes may be made to the present invention, where within the spirit and principles of the present invention, Any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
