Problems solved by technology

However, the current scheme has the following disadvantages: ①The hemostatic area of ​​the electrocoagulation rod is small and the efficiency is low, and the shape of the cauterization is irregular; ②It is difficult to further expand the fistula opening after the fistula forceps form (the cyst wall becomes an inclined plane); ③Minimally invasive scissors open the mouth It is easy to accidentally injure the peripheral blood vessels and nerves, which is difficult to operate and has potential safety hazards. Once uncontrollable bleeding occurs, it will threaten the life of the patient; ④The irregular shape of the electrocoagulation rod and the irregular edge of the fistula cut by scissors can easily lead to poor flow of cerebrospinal fluid No surgical effect, and it is easy to heal again after the operation, leading to disease recurrence; ⑤ Electrocoagulation rods, ostomy forceps, and minimally invasive scissors are used alternately for many times, and repeated use of instruments increases operation time and infection risk

Embodiment

[0031] like figure 1 and figure 2 As shown, the annular cutting apparatus for micro-invasive spider mastic surgery, including the first electrical coated burner 1 and the second electrical coalestenizer 2, and the first electrical coated burner 1 And the working position of the second electrical coaver burning 2 can be adjusted. When located in the first working position, the first electrical coated burning member 1 is turned on, i.e., as the electrode of the monopolar charging device, and the surface of hemostasis at its end is performed on its end. And a further broken operation; when located in the second working position, the first electrical coated burning 1 and the second electrical coalestentenbur burner 2 respectively open the positive and negative electrode of the bipolar electrocoagulation provider, that is, respectively The positive electrode and the negative electrode of the bipolar charging device, and on both sides of the surface of the fistula is performed between t...

Abstract

The invention discloses an annular cutting and coagulating device for minimally invasive arachnoid cyst fistulization, which comprises a first electrocoagulation burning piece and a second electrocoagulation burning piece. The first electrocoagulation burning piece is communicated with a monopole electrocoagulation providing piece at a first working position and executes electrocoagulation and crevasse at the end part of the first electrocoagulation burning piece; the first electrocoagulation burning piece and the second electrocoagulation burning piece are respectively communicated with the positive electrode and the negative electrode of the bipolar electrocoagulation providing piece at the second working position and execute electrocoagulation and cutting between the end part of the first electrocoagulation burning piece and the end part of the second electrocoagulation burning piece; and the opposite part of the end part of the first electrocoagulation firing piece and the end part of the second electrocoagulation firing piece rotates around an axis perpendicular to a plane to be fistulized. The annular cutting and coagulation device for the minimally invasive arachnoid cyst fistulization has the advantages that the structure is simple and practical, the operation complexity is reduced, the required operation space is small, the fistulization success rate is effectively increased, and the like.

Description

Technical field [0001] The present invention relates to the field of minimally invasive surgical instruments, and more particularly to a ring cutting device for minimally invasive spasilicular cysts. Background technique [0002] The intracranial vesicular cyst is a non-tumor cystic lesion of the intracranial spider form. Most of the subarachnoid cysts have found in infancy, which is formed during growth and development, resulting in a partial aggregation of the cerebrospinal fluid of the subaracine in the growth and development. The incidence of a subarachnoid cyst is as high as 0.3-2.6%. After cyst formation, it will occupy the intracranial space, which affects the normal development of the brain tissue. Some cysts will continue to increase, or the compression of the ventricular system can cause obstructive hydrocephalus, and may also cause epilepsy, local skull bulging effects. Surgical treatment is required for these clinical symptoms. [0003] Current treatment methods inclu...
