Embodiment Construction

[0030] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0031] refer to Figure 1 to Figure 8 As shown, the disposable brain surgery retractor of the present invention mainly includes: a retractor 1 , a guide 2 and a connection lock 3 .

[0032] Among them, the retractor 1 is mainly installed with the guide 2 during guidance and forms a channel through which surgical instruments can pass and move during surgery. Therefore, the retractor 1 has a sleeve structure, which is used to accommodate the installation guide. The introducer 2 and the invading tissue form a surgical channel.

[0033] As far as the retractor 1 is concerned, the retractor 1 is respectively formed with an operating end and an exposed end at both ends of the sleeve structure. Cooperate with the traction end of the introducer 2 exposed from this end to invade human tissue, and align the lesion position after the introducer 2 ...

Abstract

The invention discloses a disposable retractor for brain operation, comprising a traction-expansion device with a sleeve structure, a guide device, and a connecting lock for connecting the traction-expansion device with the guide device to form a whole, wherein the traction-expansion device has an operating end and an exposed end, the inner wall surface and the outer wall surface of the sleeve structure of the traction-expansion device respectively shrink gradually from the operating end to the exposed end, and two or more than two handles are formed at the operating end of the traction-expansion device; and the guide device has a mounting end corresponding to the operating end of the traction-expansion device to realize installation and a wedge-shaped traction end extending out from the exposed end of the traction-expansion device and capable of sealing the exposed end, and the mounting end has a mounting structure used for fixing the connecting lock. According to the invention, deep operation position can be accurately exposed, at least two operation channels for surgical operation instrument to enter fine tissues are provided, and the design of the traction-expansion device is beneficial to light source hood focusing and binocular vision.

Description

technical field [0001] The invention relates to a retractor, in particular to a disposable brain operation retractor. Background technique [0002] A retractor in a broad sense refers to a type of medical device that is in contact with human body tissue in order to obtain a surgical field of view and an operating space during a surgical operation. With the development of medical technology, the types and functions of retractors are becoming more and more abundant. [0003] However, for fine tissues of the human body, such as brain tissue, it is difficult for some retractors to provide good support for the operation. For example, in neurosurgical operations such as ventricular tumors, ventricular hemorrhage, brain subcortical tumors, intracerebral hematoma, and endoscopic surgery, it is difficult to use the existing guide to detect brain tumors and brain tumors located in the deep center of the brain. Surgery for cerebrovascular malformations. Contents of the invention ...
