Embodiment 1

[0017] See figure 1 , the mandibular hook includes a handle 1 and a working end 2, the working end 2 forms an angle of 30-60 degrees with the handle 1, preferably 45 degrees, and the working end 2 is Y-shaped, including a bifurcated end 22 and a connecting end 21 , the ports of the bifurcated ends 22 are respectively provided with hook angles 23 extending downward, and the connecting end 21 is connected with the handle 1 .

[0018] continue to see figure 1 , the connecting end 21 has an upwardly protruding radian, and the upwardly protruding radian makes the connecting end 21 into a half-moon shape, which conforms to the shape of the corner of the mouth, ensures the largest contact area, reduces damage to the corner of the mouth, and at the same time can pull the corner of the mouth to expose Deep surgical field of view.

[0019] The bifurcated angle of the bifurcated end 22 can be adjusted to suit patients with different mandibular angles. The fork angle can be adjusted by...

Abstract

The invention discloses a mandibular angle drag hook, which comprises a handle and a working end, wherein the working end and the handle form an included angle ranged from 30 degrees to 60 degrees; the working end is in a Y shape and comprises divaricating ends and a connecting end; hook angles extending downwards are respectively arranged on tips of the divaricating ends; the connecting end is connected with the handle. The mandibular angle drag hook has the advantages that (1) the reasonable design is adopted, and the working end is designed to be the Y shape and respectively goes deep into the lower edge of a mandibular body and the rear edge of a mandibular ramus, so that the wider visual operative field is exposed; (2) the connecting end is designed to be a half moon shape and conforms to a mouth shape, so that the maximum contact area is ensured, the hurt to the mouth is reduced, meanwhile, the mouth can be pulled and opened, and the deep visual operative field is exposed; (3) since the area of the working end is larger than that of a traditional drag hook, a power drill can be fully separated from soft tissues, accidental injury is avoided, and masseter and buccal mucosa can be protected.

Description

technical field [0001] The present invention relates to medical instruments, and more particularly, to a retractor used in surgery. Background technique [0002] Surgical retractor is one of the most commonly used instruments in surgery. It exposes the operator with the largest possible field of view in the smallest possible incision, and is closely related to improving surgical quality, shortening surgical time, and reducing surgical trauma. Different surgical sites need to use different retractors. Due to the anatomical relationship of the oral and maxillofacial region, the surgical operation space is narrow. There is no special hook for mandibular angle modification when performing operations on the mandibular angle area through the intraoral approach. The disadvantages of other traditional retractors are as follows: ①In order to penetrate into the mandibular angle, it is usually designed to be slender, but it cannot fully expose the surgical field of view (mandibular br...
