Retractor for neuroendoscopy operation of cerebral hemorrhage

Technical Field

The utility model relates to a retractor technical field specifically is a neural scope retractor for operation of cerebral hemorrhage.

Background

At present, craniocerebral operation under neuroendoscopy is an important direction for the development of minimally invasive neurosurgery, and the core of the technology is to further reduce the trauma of the prior operation approach, enlarge the exposure of the disease condition and increase the chance of directly cutting off the pathological changes. Neuroendoscopy mainly comprises external sheath surgery and internal sheath surgery, wherein the internal sheath surgery is mainly used for lesions without natural physiological lacuna channels, such as intracerebral lesions (such as cerebral hemorrhage) and intracerebroventricular lesions (such as tumors), and has the defect of limiting the application range, so that a retractor is often required to be applied in the operation process.

At present, current retractor for neuroendoscopy operation need be at two erection bracing poles that lead between the arm after strutting the incision to ensure the angle that leads the arm to strut, but, above-mentioned technical scheme is comparatively troublesome in the in-service use process, and the space that its itself occupied is also great, and the art field when the influence operation goes on exposes, can not improve the agility of medical personnel's operation, and for this reason, we provide a retractor for neuroendoscopy operation of cerebral hemorrhage.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the retractor for neuroendoscopy cerebral hemorrhage shown in the figures comprises a first handle 1 and a second handle 2 which are hinged to each other, wherein a grip ring 3 which is integrally formed is fixedly mounted at the rear ends of the first handle 1 and the second handle 2, a retraction assembly 4 is mounted at the front ends of the first handle 1 and the second handle 2, and a locking assembly 5 which is used for preventing an occupied space from being too large and is convenient for a doctor to adjust is mounted between the first handle 1 and the second handle 2.

Wherein, the locking component 5 comprises two locking plates 6, one end of each of the two locking plates 6 is fixedly connected with the first handle 1 or the second handle 2, the opposite sides of the two locking plates 6 are provided with arc parts, the safety in use is improved, each locking plate 6 is provided with a plurality of jacks 7, a screw part 8 is arranged in the jack 7, the screw part 8 is a fastening bolt or a screw and the like, when in operation, the thumb and the middle finger of one hand of a doctor are respectively inserted into the two holding rings 3 and drive the retracting component 4 to expand the incision to the actual required size, and then the other hand rotates the screw 8 to lock the two locking plates 6, therefore, the device not only occupies small space and provides a wider surgical field for the doctor, but also has simple operation and is convenient for improving the operation rapidity of the doctor.
