Background
In more than ten years, with the continuous development of endoscopic technology and medical instruments, over 80% of thoracic surgery lung operations can be considered for minimally invasive treatment, however, minimally invasive surgery is divided into three holes, single operation hole and single-hole thoracoscope, and minimally invasive surgery needs to use an endoscopic linear cutting closer to cut off tissues such as pulmonary vessels, bronchus and the like to perform operations such as lung segment resection, lung lobe resection and the like.
As shown in fig. 7 to 9, the cutting closer includes a closer body 100 and an extension rod 200, the head of the extension rod 200 can be used with all types of nail boxes 300, a movable joint 400 is further formed on the extension rod 200, and the nail boxes 300 can form a certain included angle with the extension rod 200 through the movable joint 400, so as to facilitate the operation of the doctor. The front opening of the magazine 300 is divided into an upper portion and a lower portion, the upper portion is a thin anvil 310, and the lower portion is a staple cartridge 320.
In operation, the tissue to be cut and closed must be sufficiently free around and separated from a certain tissue gap, and the anvil 310 of the linear cutting and closing device can safely pass through and engage to break the tissue. Due to the limitation of incision in the thoracoscope operation, especially a single-hole thoracoscope, the operation space and angle are extremely limited, when the operation is performed, especially when the operation is performed on a lung segment, the linear cutting closer can only be operated in a relatively fixed direction, and in addition, the anatomical structures of the pulmonary blood vessel and the bronchus are complex, especially when target tissues needing to be cut off are invaded by tumors, peripheral lymph nodes are large or are tightly adhered, the linear cutting closer is difficult to accurately pass through and bite the tissues needing to be cut off, and the target needing to be cut off and peripheral normal tissues are easy to be damaged, so that the pulmonary blood vessel bleeding is caused, the operation is transferred to be open, and the operation is even failed, and the life of a patient is threatened. Therefore, how to safely, effectively and quickly realize the safe and accurate passing and occlusion of the tissue needing to be cut and closed by the endoscope linear cutting suturing device becomes a difficult problem for clinicians, especially for less experienced surgeons.
In view of the above, the present inventors have made extensive studies on the above-mentioned drawbacks of the prior art, and have made this invention.
SUMMERY OF THE UTILITY MODEL
The main object of the utility model is to provide a cutting closer safety guiding device, it has the characteristics that the nail anvil of guide cutting closer removed, has reduced the operation degree of difficulty and has improved the operation security.

when the surgical instrument is used, a doctor carries out tissue dissociation on a cutting part through other surgical instruments to form a channel for a guide device to enter, the guide device penetrates through the channel under the separation assisting effect of a guide head, the doctor drives the first clamp rod and the second clamp rod to be in a closed state through the first clamp arm and the second clamp arm, and a nail anvil of the cutting closer slides in a sliding accommodating cavity of the guide device until the cutting position is reached. After the cutting position is reached, the first clamp body and the second clamp body are loosened, and the nail anvil can smoothly separate from the sliding containing cavity to start working. Therefore, through the protection effect of the guide device, the head part of the nail anvil is attached in the sliding containing cavity, the interference of tissues around a target object on the advancing of the nail anvil is avoided, the risk that the nail anvil of the cutting closer damages a blood vessel in the operation process can be reduced, and the operation safety is greatly improved.
Use the utility model discloses can avoid the nail anvil of chamber mirror linear cutting closer to cause the tissue that needs to break and the damage of peripheral important anatomical structure when passing through the tissue clearance alone to a certain extent, reduce the probability that vascular damage leads to intraoperative hemorrhage greatly, reduce complicated chamber mirror lung operation, especially the lung section or unite the degree of difficulty that the inferior section was removed in the operation, make things convenient for the operation, wholly shorten the operation time, reduce the transfer chest ratio.
The two guide heads are mutually contacted when the first clamp body and the second clamp body are closed, so that the two guide heads jointly play a role in separating and guiding, and the guide device can safely, effectively and quickly penetrate through a target gap.
And thirdly, the nail anvil can only pass in and out of the sliding accommodating cavity from the opening of the sliding accommodating cavity from one side of the first clamp rod and one side of the second clamp rod, and the nail anvil cannot pass through the weight-reducing gap when the first clamp rod and the second clamp rod are closed. Through setting up and subtract heavy clearance, reduced the weight of first pincers pole and second pincers pole for guiding device is light more nimble, is favorable to doctor's operation.
