Description

Stabilizing device for connecting spreader and micro-endoscope

Technical Field

The utility model relates to a stabilizing device, in particular to a stabilizing device for connecting a PIPELINE adjustable spreader with a micro-endoscope, and belongs to the technical field of medical equipment.

Background

Minimally invasive spinal surgery was first initiated in the fifties of the last century, and, unlike traditional surgical procedures, does not require extensive soft tissue exposure, and is accomplished only through small incisions to achieve diagnosis and treatment of disease. The expandable channel technology is an important means for assisting the minimally invasive spine surgery, and the technology can enlarge the exposed surgical field by means of the tension of soft tissues around the surgical area through a special expandable channel instrument, but does not cause the exposure increase, and furthest controls the surgical trauma. In recent years, with further development and research of expandable channel technology, many high-difficulty spinal surgeries can be solved by minimally invasive means, such as diagnosis and treatment of spinal tumors, basic concepts of minimally invasive surgery treatment of the through-channel spinal have been realized clinically, the minimally invasive surgery of the through-channel spinal can greatly slow down the operation time, reduce the operation wound, and the wound healing after the operation is fast, so that the patient benefits to the greatest extent.

Currently, the primary factor limiting the application of minimally invasive trans-spinal surgery is the intraoperative exposure. The spine operation position is special, the anatomical structure is complex, the operation area often relates to spinal cord and nerves, the operation requirement is high, and the operation difficulty is high. Transvertebral Kong Chuiti fusion (TILF) and posterior decompression fusion are currently commonly used procedures with the aim of relieving spinal cord or nerve root compression, but whichever procedure is intended to achieve minimally invasive procedures, good surgical vision must first be achieved, and vision control first relies on the establishment of a channel system. PIPELINE of DePuy ^TM The System is one of the most commonly used channel systems in the current domestic minimally invasive channel surgery and is mainly characterized in that the spinal surgery access is simplified, and the PIPELINE adjustable spreader has two stagesAnd is provided with a relatively complete minimally invasive surgical instrument. The above-mentioned channel system is often operated with a headlight and a magnifying glass carried by the operator, and this way has the following disadvantages: (1) the surgical field of view is limited to the operator himself, and the surgical exposure is limited; (2) the head-wearing magnifier lacks stability, and needs years of clinical experience to obtain skilled operation skills, so that the operation difficulty is increased intangibly; (3) the limited space is not conducive to recording the procedure.

Through clinical practice for many years, we find that the application of the auxiliary channel system of the endoscope system is beneficial to increasing the exposure in the operation, the external display screen of the endoscope system enables the visual field not to be limited to the operator, the operation of the endoscope system is convenient, the operation difficulty is greatly reduced, and the operation process can be completely recorded. The general flow of the operation mode is to firstly establish a channel system, put channel instruments into an operation position, put a light source and a microscope into the channel, and finally connect the microscope with an external display screen, so that an operator can operate spinal cord and nerves under direct vision by means of the external display screen. However, this method still has disadvantages, mainly the lack of connection between the channel and the microscope, resulting in a lack of stability of the surgical field. Unlike the endoscopic minimally invasive surgery technique of other parts, since the spinal surgery requires a fine manipulation of nerves, the requirement for the stability of the microscopic endoscope field of view is higher. In general laparoscopic surgery, such as knee arthroscopy or laparoscope, the microscope is not usually fixed during the surgery, and the visual field direction is manually controlled by the operator or an assistant to obtain higher flexibility. But spinal surgery is mainly operated on nerves, the scope of an operation area is fixed, frequent replacement directions of a microscopic endoscope are not needed, in addition, a long-time fixed and stable visual field is needed during operation in a channel, shaking generated by manually controlling the microscopic endoscope has a large influence on operators, and minimally invasive operation of the operation is limited.
