Description

Bone fragment taking-out forceps for hallux valgus operation

Technical Field

The utility model relates to a medical plastic apparatus, in particular to a bone-crushing forceps for hallux valgus operation.

Background

Hallux valgus refers to a forefoot deformity in which the hallux deflects outward beyond the normal physiological range at the first metatarsophalangeal joint, commonly known as the "big foot bone", a complex forefoot deformity involving a variety of pathological changes.

The hallux valgus is caused by many factors, such as inheritance, shoes passing through narrow high heels, abnormal foot structure, among others, by several other reasons: such as rheumatoid arthritis of the first metatarsophalangeal joint, gout, etc.

Conservative treatment for hallux valgus includes: selecting loose or even toe-exposed shoes; wearing a hallux valgus protective pad, a toe separating pad and using an abduction brace at night; lateral hammer toes, wearable toe caps, and the like. However, conservative treatment generally provides only temporary relief of pain, and does not provide long-term definitive orthopedic effects. It is clinically even encountered in some patients with hallux valgus that the pain is aggravated by wearing a split toe pad or abduction brace.

At present, for moderate and severe patients with hallux valgus, the operation mode is adopted, so that the bony deformity can be fully corrected, the rebalancing of soft tissues is carried out, and the possibility of relapse of hallux valgus is reduced to the maximum extent, so as to reduce pain and prevent further development of deformity.

In hallux valgus orthopaedy, broken bone taking-out forceps for hallux valgus operation are commonly used for taking out broken bones generated in an operation process, but because the broken bones are different in size and shape, the excessively thin broken bones are difficult to take out when the existing equipment is used for taking out the bones.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a broken bone takes out pincers for hallux valgus art, including two clamping parts, two connecting portion and two tong arms, the one end of clamping part is connected with the one end of connecting portion, and the other end of connecting portion is connected with the one end of tong arm, two connecting portion intercrossing connection, and tong arm and clamping part can rotate around the junction of two connecting portion interconnect, and the other end of tong arm is provided with the grip ring, and the inboard of two clamping part intercommunications is provided with the inner chamber, is provided with anti-skidding tooth around the inner chamber.

Furthermore, the clamping part is bent and forms an angle R with the plane of the two clamp arms, and the range of the angle R is 10-90 degrees.

Further, the clamping part is rigidly connected with the connecting part.

Further, the connecting part is rigidly connected with the clamp arm.
