Surgical tool for taking ilium block

Abstract

The invention discloses a surgical tool for taking ilium blocks, which comprises two osteotome assemblies, and the two osteotome assemblies are respectively arranged on a cross rod and can move along the cross rod; the osteotome assembly comprises an osteotome and an adjusting device, and the adjusting device comprises a fixing part used for fixing the osteotome and keeping the axis of the osteotome perpendicular to the transverse rod and a moving part connected with the transverse rod in a sleeved mode. The movable part is provided with a fastener for limiting the adjustment device to be fixed relative to the cross rod at any position; and scales are arranged on the cross rod. The product has the advantages that bone knives at the two ends are knocked at the same time, and patient injuries and fracture risks are reduced; and 2, the scales of the connecting rod can realize the width quantification of the bone block, so that the ilium block is prevented from being too large or too small;.

Description

technical field [0001] The invention relates to a surgical tool, in particular to a surgical tool for taking iliac bone blocks, and belongs to the technical field of surgical tools. Background technique [0002] In actual clinical work, for large bone defects, cervical subtotal resection, upper cervical fusion, etc., autologous bone transplantation is often required. bone position. [0003] Ilium bone grafting is the most commonly used autologous bone grafting operation in orthopedics. It is necessary to take a corresponding iliac bone block according to the actual situation. The steps are as follows: the patient is placed in the supine position, routinely disinfected, and the drape is spread along the lower edge of the iliac crest. Shaped incision, about 10 cm long, cut and separated layer by layer until reaching the ilium, peeling off the periosteum of the iliac bone, taking the bone size according to the plan, inserting the osteotome in the front and back of the ilium re...

AI Technical Summary

Problems solved by technology

[0004] The current problems of ilium extraction are as follows: 1. Three osteotomies are required, which may cause bone compression or fracture, especially for patients with osteoporosis; If the iliac bone is too large, it will cause great damage to the patient, or if the iliac bone is too small, it cannot meet the needs of bone grafting

[0005] CN201922096444.0 A box-type iliac bone extractor. This patent uses a rectangular working end to extract the ilium, and the inner and outer parts are likely to cause obstruction or damage the inner and outer tissues.
