Problems solved by technology

However, intrathecal surgery has the following disadvantages: the operating space is narrow; the configured suction device is small in diameter, which is difficult to cope with active arterial bleeding during the operation, and it is difficult to stop bleeding and cannot absorb blood clots; The dedicated channel of the endoscope working sheath is limited; and because the light of the endoscope passes through the water (cerebrospinal fluid) environment, a small amount of bleeding in the water (cerebrospinal fluid) environment causes the surgical field to be unclear
However, even the improved working sheath cannot adjust the size of the opening, and there are some defects, which make it difficult to use and promote in actual work

Embodiment Construction

[0018] Such as figure 1 As shown, a neuroendoscopic surgery auxiliary spreader includes two linear spreader feet 1, 2, the cross-section of the two spreader feet 1, 2 is a semicircle with the same radius, and the two spreaders The semicircular openings of the cross sections of the spreaders 1 and 2 are opposite; the tops of the two spreader feet 1 and 2 are provided with an opening adjustment mechanism that controls the opening and closing of the two spreader feet 1 and 2, and each spreader The ends of the outer extensions of the legs 1 and 2 are respectively provided with abduction adjustment mechanisms for controlling the size of the openings at the bottom of the legs 1 and 2 of the spreader.

[0019] The outer periphery of each spreader foot 1, 2 is coated with a transparent rubber film.

[0020] The opening adjustment mechanism includes two connecting arms 7 integrally formed with the two adjusting arms 4 or with the two adjusting arms 4 respectively, and the two conn...

Abstract

The invention belongs to the field of medical instruments and relates to an auxiliary unfolding device of a neuroendoscopic surgery. An unfolding device system provides a good visual field for the neuroendoscopic surgery, provides protection for brain tissues and can also be used in a keyhole surgery under a microscope. The unfolding device comprises two unfolding device legs, the cross sections of the two unfolding device legs are semi-circles with the same radius, and semi-circular openings of the two cross sections of the unfolding device are opposite. An opening adjusting mechanism controlling opening and closing of the two unfolding device legs is arranged on top of the two unfolding device legs. An external-extending adjusting mechanism for controlling the opening size of the bottoms of the unfolding device legs is respectively arranged on top of each unfolding device leg. The auxiliary unfolding device is clever and reasonable in structure and forms an artificial gap without important structures on the periphery, and the gap can be adjusted appropriately. The auxiliary unfolding device widens a use range of the neuroendoscopic minimally invasive surgery and can be applied to the keyhole surgery under the microscope.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an auxiliary spreader for neuroendoscopic surgery. The spreader system provides a good field of vision for neuroendoscopic surgery and protects brain tissue, and can also be used for keyhole surgery under a microscope. . Background technique [0002] Neuroendoscopic surgery is an important direction for the development of minimally invasive neurosurgery. The neuroendoscope can go deep into the operation area and observe the anatomical structure of the operation area at close range, so that "watching TV while standing outside the door becomes watching TV inside the house" in the past. However, the neuroendoscope has the defect of not being able to observe the surrounding conditions of the channel, so the neuroendoscope and auxiliary instruments are operated in the working sheath, and the protection of the working sheath is used to prevent the surgical instruments from damaging the ...
