Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a surgical suction device. Background Technology

[0002] Currently, electrocautery is widely used in surgery for procedures such as dissecting subcutaneous tissue and fascia, opening joint capsules, and electrocoagulation for hemostasis. However, during electrocautery or electrocoagulation, the incomplete combustion of soft tissues such as fat and protein generates a large amount of inhalable particulate matter. Approximately 95% of these particles have a diameter between 0.3 and 5 micrometers. This not only results in an unpleasant odor permeating the operating room, but the generated smoke can also obstruct the surgeon's vision, affecting the precision of surgical procedures.

[0003] Currently, the primary method for handling surgical fumes is the use of specialized electrosurgical suction devices. However, these devices are expensive, unaffordable for ordinary families, especially under a Diagnosis-Related Groups (DIG) billing system where cost-effectiveness is a crucial consideration. Furthermore, electrosurgical suction devices require a dedicated surgical assistant, increasing labor costs. The device is also susceptible to contact with the electrosurgical unit, impacting the surgical team's efficiency and potentially causing accidents. Therefore, under the DIG billing system, designing a surgical suction device that effectively removes fumes during surgery, is fully controllable by the surgeon without interfering with the procedure, and is cost-effective, has become a pressing issue for those skilled in the art.

[0004] Therefore, it is necessary to design a surgical suction device to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes a surgical suction device. It adopts a design of suction head and blade head, which allows doctors to remove the smoke generated by the suction head while using an electrosurgical knife for cutting or coagulation. This eliminates the need for another doctor to hold an electrosurgical suction device to remove the smoke, avoids interference from the doctor using the electrosurgical knife, improves surgical accuracy and reduces labor costs.

[0006] The technical solution of this utility model is: This utility model proposes a surgical suction device, comprising: An electric knife, comprising: a hand handle, a connector, a blade head, and a push switch, wherein the push switch is disposed on the outer wall of the hand handle, the connector is connected to one end of the hand handle, a power source is connected to the hand handle away from the connector, and the blade head is detachably connected to the connector. The suction section is connected to the blade head and is used to draw in the smoke generated when the blade head is working.

[0007] Preferably, the blade head includes: Rectangular plate; A cutting blade is connected to one end of the rectangular plate, and the end of the cutting blade is set to be arc-shaped; The connector is detachably connected to the end of the rectangular plate away from the cutting blade.

[0008] Preferably, the suction part includes: A suction tube, one end of which has a suction port, the length of which is greater than the outer diameter of the suction tube, and the suction port is located on one side of the cutting blade; The fixing sleeve has two parts, which are arranged at equal intervals. Each fixing sleeve has a rectangular opening, which is connected to the rectangular plate. One side of each fixing sleeve has an arc-shaped surface, and the arc-shaped surfaces of the two fixing sleeves are connected to the two sides of the outer wall of the suction tube. A connecting tube is attached to the outer wall of the connector, and the outer wall of the connector is shaped like a frustum. A conveying pipe, one end of which is connected to the connecting pipe, and a negative pressure device is connected to the outside of the conveying pipe.

[0009] Preferably, a circular guide groove is provided on the outer wall of the hand handle, the circular guide groove is arranged along the length direction of the hand handle, an observation groove is connected to one side of the circular guide groove, the circular guide groove is inserted into the delivery tube, and a transparent elastic band is sleeved on the outer wall of the hand handle, the transparent elastic band is in contact with the outer wall of the delivery tube.

[0010] Preferably, the width of the observation groove is smaller than the inner diameter of the circular guide groove and the outer diameter of the conveying pipe.

[0011] This utility model has the following advantages and effects compared with the prior art: (1) The design of the suction head and the blade head allows the doctor to remove the smoke generated by the suction head while using the electrosurgical knife to cut or coagulate. This eliminates the need for another doctor to hold the electrosurgical suction device to remove the smoke, thus avoiding interference from the doctor using the electrosurgical knife. This improves surgical accuracy and reduces labor costs.

[0012] (2) The suction unit is connected to the blade head, which can absorb the smoke generated during the cutting process in real time, preventing the smoke from spreading in the surgical area, protecting the operating room environment, and reducing the risk of doctors and patients inhaling harmful particles.

[0013] (3) The design of the suction device takes into account the ease of operation and the intuitiveness of monitoring. The circular guide groove and observation groove on the outer wall of the hand handle facilitate the placement and passage of the delivery tube.
