Description

Suction head with forceps holder function for thoracoscope surgery

Technical Field

The utility model relates to a thoracoscope surgery is with attracting head with forceps holder function.

Background

In the world today, lung cancer is one of the most prevalent malignancies. According to the statistical data published by CA Cancer J Clin in 2018, the following are shown: the number of new lung cancer outbreaks in the world is nearly 210 million, accounting for 11.6% of 36 main malignant tumors; lung cancer is 176 million lethal, accounting for 18.4% of 36 major malignancies. Morbidity and mortality are first; in east asia, lung cancer is the highest incidence malignancy in men and the third highest incidence in women.

The operation is the preferred treatment mode for the patients with early and middle lung cancer. The life cycle of the patient can be effectively prolonged by cutting off the lung lobes where the focus is located and combining complete lymph node cleaning. Traditional lung cancer surgery usually uses posterolateral incisions, which have a length of 15-20cm and ensure the exposure of the operative field by cutting 1-2 ribs. The operation mode has large damage to patients, and has high incidence of postoperative pain, affected side chest wall numbness and other complications.

In the last decade or more, thoracoscopic surgery (VATS) has become the standard means of lung cancer surgery. The VATS incision is small (generally only 3-4 cm), ribs do not need to be cut off, the same treatment effect can be achieved, the wound on a patient is small, the postoperative recovery is fast, the complication incidence rate is low, and the hospitalization time is short. VATS rates account for more than half of thoracic surgery. Not only lung cancer, but almost all thoracic surgery, such as esophageal, mediastinal, etc., can be done under thoracoscopy.

Common VATS is divided into a single hole (the lens and all operating instruments enter from a main incision of 3-4cm, the main knife is mainly operated by holding an electric hook or an ultrasonic knife with the right hand, the suction head with the left hand is used for sucking bleeding and smoke and assisting in exposing the surgical field, the camera with the right hand is used for providing the visual field with the assistant, the visual field is exposed with the assistance of the left hand), the hand-held surgical instrument comprises three types, namely a double-hole (a small incision of about 1cm is made for a lens to enter, and other instruments enter from independent incisions) and a three-hole (on the basis of the double-hole, another small incision of about 0.5cm is made for an aspirator to enter. the main knife holds an electric hook or an ultrasonic knife to carry out main operation on the right side, and the left hand holds the instrument to assist in exposing a surgical field. Among them, single-hole and three-hole are the mainstream modes of clinical thoracoscope operation at present.

In VATS, the function of a negative pressure aspirator is indispensable. The bleeding during the operation or the smoke generated by the high-temperature cutting of the electric knife are sucked from the visual field of the operator by the suction apparatus. The suction head, i.e. the front end of the suction apparatus, is held by a surgeon to perform a specific suction operation. The suction head of the suction apparatus generally adopts a tube body, the front end of the tube body is an input end, the rear end of the tube body is an output end, and the output end is connected with a negative pressure tube to provide negative pressure for the input end.

The suction head has a pressing and lifting function in addition to the most basic suction function. The main surgeon or the assistant holds the suction head by hand, and presses the tissue with the front end of the suction head while sucking, so as to help expose the visual field. However, in many cases, the effect of sufficiently exposing the visual field cannot be achieved by a simple pushing or lifting operation, and some pulling operation of the tissue is required. At this time, the conventional suction head does not perform a good exposure function. For example, the lymph nodes need to be lifted to allow for cutting below them. At this time, the upward movement cannot be used due to lack of an acting point. Because the suction head lacks the function of clamping, the lymph node can only be supported backwards on the chest wall, and the lymph node is kept in a lifting state by utilizing friction force, so the practical operation is very inconvenient.

Because the VATS incision is small, too many instruments cannot be inserted simultaneously; furthermore, VATS is generally completed by only two doctors, the operable instruments are limited at the same time, and it is inconvenient to add an instrument for tissue traction in addition to the original instrument. If the suction head is taken out temporarily, the operation is carried out by using the forceps, on one hand, the operation rhythm is influenced by the increase of the in-out times of the instrument, the operation time is prolonged, on the other hand, the partial bleeding is accompanied when a lot of cuts are carried out, and if the suction head is lost, the bleeding can influence the operation visual field. The suction head can not reach the purpose of exposure, so the operation can be suspended and the instruments can be replaced; if there is active bleeding at the root of the lymph node (common in the art), the visual field will be covered by fresh blood after the grasper is replaced, and exposure still cannot be achieved. Therefore, if the suction head has the function of pulling in addition to the existing functions of sucking blood and smoke, and pushing and lifting tissues, the VATS can be performed conveniently.

In addition, in VATS, it is often the case that suturing within the thoracic cavity is required. In a general open surgery, when a needle is inserted into a tissue to complete suturing and ready to be withdrawn, the left hand holds forceps to assist in grasping an exposed needle tip and withdrawing the needle. However, in VATS, the suction head held by the left hand of the main knife can only make the needle point relatively exposed on the tissue surface by pressing the lung tissue downwards, and the needle point cannot be clamped out as in open surgery; at this time, the main knife can only let the needle holder of the right hand release the root of the suture needle and move to the needle point to pull out the needle. However, in many cases, because the amount of the tissues to be sutured is large, the tissues can be compressed only under the joint extrusion of a needle holder at the root of the needle and a suction head near the needle point, and the needle point can be exposed out of the surface; once the needle holder releases the root of the needle, the tissue will bounce due to the sudden loss of force, re-submerging the needle tip into the tissue. In this case, if the suction head can also have a clamping action, the right hand does not have to release the needle holder, and the suction head can very simply clamp the needle tip and pull the needle out of the tissue.

The suction head with the function of clamping jaws is more suitable for sleeve-shaped lobectomy under a thoracoscope. The difficulty with this procedure is the manual suturing of the bronchial stumps on both sides. Ten or more suturing actions are required to complete one circle of anastomosis. After each sewing and knotting, the redundant suture is not immediately cut off, but is kept for positioning and pulling. Therefore, as the suturing process continues, the number of the pulling wires in the surgical field increases. In this case, thoracoscopic suturing using conventional instruments becomes more difficult: in the traditional thoracoscopic suture, the needle holder held by the right hand is required to release the root part of the needle and move to the needle tip part; however, since there are many pulling wires in the operation area, the needle holder cannot be directly translated to the needle tip after releasing the needle root, and generally needs to exit the patient body through the operation hole first, then search again for a path which does not affect the pulling wires to enter, and grasp the needle tip before. This procedure is not only time consuming, but also can easily cause inadvertent contact with the tissue and the pulling wire during the insertion and withdrawal of the needle holder, resulting in displacement of the suturing needle and the need to withdraw the needle for re-suturing.
