Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a suction grasping forceps for surgery. Background Art

[0002] A suction grasping forceps for surgery is a commonly used surgical instrument, which includes a pair of controllable opening and closing forceps heads to grasp the target tissue between the forceps heads, so as to apply a mechanical clamping force to the tissue.

[0003] In modern surgical operations, especially in the field of thoracic surgery, with the development of minimally invasive technology, thoracoscopic surgery has become one of the standard means for treating lung diseases. Such surgeries usually adopt a single-hole or single operating hole, and all necessary surgical instruments must enter the patient's body through this narrow channel to perform complex operations, such as lobectomy or segmentectomy. During such surgical procedures, the operating space of the surgeon is strictly limited, and each surgical instrument needs to be used precisely and efficiently.

[0004] Currently, in thoracoscopic surgery, the surgeon often holds a suction device in one hand to clear the blood, tissue fragments and smoke in the surgical area and keep the surgical field clear; holds an energy instrument such as an electric hook or a harmonic scalpel in the other hand to complete the separation, cutting and hemostasis of tissues. If it is necessary to grasp and hold tissues for traction and exposure, the surgeon needs to hand over the suction device to an assistant to hold, and then change to a tissue grasping forceps for operation. In addition, the assistant holds the suction device to assist in sucking smoke or blood, etc., to ensure a clear field of view. Such a separated tool has problems such as inconvenient operation, low efficiency, and mutual interference between instruments. Content of the Utility Model

[0054] A suction grasping forceps for surgical use is a medical device specifically designed for surgical operations. Its main function is to grasp, hold, traction or fix tissues during the operation. The forceps usually consists of several key components: the forceps head, the forceps rod and the handle. The forceps head is the part that directly contacts the tissue and may have different shapes and sizes to meet the needs of different surgeries. The forceps rod is a long rod connecting the forceps head and the handle, which allows the doctor to operate without directly contacting the surgical area. The handle is the part that the doctor holds and controls the opening and closing of the forceps.

[0055] Grasping forceps have a very wide range of applications in surgery and can be used for:

[0056] In open surgery, such as gynecological surgery, grasping forceps can be used for surgical traction and dissection of the ovaries around the lesion site.

[0057] In gallbladder surgery, grasping forceps can be used to grasp and pull tissues, especially in laparoscopic surgery.

[0058] In hysteroscopic surgery, grasping forceps can be used for tissue cutting, clamping and suturing operations.

[0059] In gynecological surgery, uterine grasping forceps can be used to grasp uterine tissues or organs, especially in cesarean section surgery.

[0060] In thoracic surgery, the surgical suction grasping forceps combines the functions of a suction device and grasping forceps, and is used to hold tissues while clearing blood, tissue debris and smoke generated by energy instruments, keeping the surgical field clear.

[0061] Grasping forceps are usually made of high-strength materials such as stainless steel or titanium alloy, which have good corrosion resistance and sufficient strength to withstand the pressure and wear during the operation.

[0062] Since grasping forceps directly contact the patient's tissues during surgery, they need to undergo strict cleaning and disinfection procedures to ensure that they do not cause infection.

[0063] Figure 1 Schematic diagram of the structure of a surgical suction grasping forceps provided by an embodiment of the present utility model; Figure 2 Schematic diagram of the structure of the forceps head of a surgical suction grasping forceps provided by an embodiment of the present utility model; Figure 3 Schematic diagram of the structure of the sleeve rod of a surgical suction grasping forceps provided by an embodiment of the present utility model. The above schematic diagrams do not represent the actual proportions of the actual products.

[0064] As Figures 1 to 3 shown, a surgical suction grasping forceps according to an embodiment of the present utility model includes: a sleeve rod 1, a forceps head 2, a first forceps handle 3, a second forceps handle 4 and a transmission assembly 5.

[0065] Among them, the sleeve rod 1 is designed as a hollow structure with a hollow cavity, which allows blood, tissue fluid, smoke and other surgical by-products to be sucked out through the hollow cavity, keeping the surgical area clean and the field of view clear.

[0066] The sleeve rod 1 has two ends. The first end is close to the surgical site and is provided with a forceps head 2 for grasping tissues; the second end is far from the surgical site and is usually located outside the surgical incision for easy operation by the doctor.

[0067] A suction hole is provided near the first end, which is the entrance for the suction fluid to enter the sleeve rod 1. An aspirator connection part 7 is provided at the second end, which is used to connect with an external suction device to form a complete circuit of the suction system.

[0068] The transmission assembly 5 is arranged inside the sleeve rod 1, one end of the transmission assembly 5 is connected to the first clamp handle 3 and the second clamp handle 4, and the other end of the transmission assembly 5 is connected to the clamp head 2. When the doctor squeezes the first clamp handle 3 and the second clamp handle, the transmission assembly 5 converts this linear movement into the closing of the clamp head 2, ensuring that the doctor's operation can be accurately reflected at the end of the surgical instrument.

[0069] In one embodiment, the first clamp handle 3 and the second clamp handle 4 are made of elastic metal material; one end of the first clamp handle 3 and one end of the second clamp handle 4 are fixedly connected to the outer wall of the sleeve rod 1, and the other end of the first clamp handle 3 and the other end of the second clamp handle 4 are close to the second end, so that the first clamp handle 3 and the second clamp handle 4 are set at an acute angle to the sleeve rod 1; the other end of the first clamp handle 3 and the other end of the second clamp handle 4 are connected to one end of the transmission assembly 5.

[0070] The elastic metal material can ensure that the pliers handle deforms when subjected to force, and can quickly return to its original shape when the external force is removed. The elastic memory of the material allows it to quickly return to its original shape, thereby automatically opening the pliers head 2, and the opening of the pliers head 2 can be achieved without the need for an additional mechanical reset structure or power source. Since no additional reset mechanism is required, the doctor can reduce the force during operation, thereby reducing hand fatigue, especially during long-term surgery.

[0071] This type of metal material usually has high strength, fatigue resistance and good biocompatibility, is suitable for long-term surgical operations, and will not cause adverse reactions to patients.

[0072] The clamp head 2 includes a fixed clamp head 21 and a movable clamp head 22 ; the fixed clamp head 21 is fixedly arranged at the first end; the movable clamp head 22 is rotatably arranged at the first end and connected to the other end of the transmission assembly 5 .

[0073] The fixed forceps head 21 is a part of the forceps head 2, which is fixedly mounted on the first end of the sleeve rod 1, that is, the end close to the surgical site. The position and direction of the fixed forceps head 21 remain unchanged throughout the life cycle of the instrument, and it is the basis for providing stable support when grasping tissue.

[0074] The movable forceps head 22 is also located at the first end of the sleeve rod 1, but it is different from the fixed forceps head 21 and can rotate around an axis. The movable forceps head 22 is connected to the other end of the transmission assembly 5. When the doctor operates the first forceps handle 3 and the second forceps handle 4, the force is transmitted to the movable forceps head 22 through the transmission assembly 5, so that the movable forceps head 22 opens and closes relative to the fixed forceps head 21, thereby grasping or releasing the tissue.

[0075] When the doctor squeezes the first clamp handle 3 and the second clamp handle 4, the movable jaw 22 approaches the fixed jaw 21 through the transmission assembly 5, and the gap between them decreases, thereby grasping the tissue. When the doctor relaxes the first clamp handle 3 and the second clamp handle 4, the gap between the movable jaw 22 and the fixed jaw 21 increases under the restoring force of the elastic metal material, releasing the tissue.

[0076] In one embodiment, the sleeve rod 1 includes a first sleeve rod 11, a second sleeve rod 12, a third sleeve rod 13 and a connecting sleeve 6; the first sleeve rod 11 and the second sleeve rod 12 are parallel to each other and arranged at intervals, and there is an installation gap 14 between the first sleeve rod 11 and the second sleeve rod 12; one end of the first sleeve rod 11 and one end of the second sleeve rod 12 are connected to the third sleeve rod 13 through the connecting sleeve 6; a through hole for passing through the transmission assembly 5 is provided at one end of the connecting sleeve 6 close to the first sleeve rod 11; the through hole corresponds to the position of the installation gap 14; one end of the transmission assembly 5 passes through the above through hole and the installation gap 14 and is connected to the first clamp handle 3 and the second clamp handle 4.

[0077] The first sleeve rod 11 and the second sleeve rod 12 are parallel and arranged at intervals, forming an installation gap 14 therebetween. This design can provide sufficient space for the transmission assembly 5 to ensure its smooth operation, while increasing the rigidity of the entire instrument and reducing the shaking during operation.

[0078] The third sleeve rod 13 is connected to one end of the first sleeve rod 11 and the second sleeve rod 12 through the connecting sleeve 6, ensuring the structural stability of the sleeve rod 1. The third sleeve rod 13 is a hollow tube with a circular cross section and is designed as the main body part of the suction grasping forceps for carrying the suction part and the jaw 2. The circular cross section helps to reduce the resistance during rotation and facilitates the doctor's multi-directional operation during the operation.

[0079] The connecting sleeve 6 is located at one end of the first sleeve rod 11 and the second sleeve rod 12, and a through hole is provided at one end close to the first sleeve rod 11 for the transmission assembly 5 to pass through. The position of the through hole corresponds to the installation gap 14 (i.e., the through hole is between the first sleeve rod 11 and the second sleeve rod 12), ensuring that the transmission assembly 5 can pass through here to realize the connection with the first clamp handle 3 and the second clamp handle 4.

[0080] Specifically, the first connecting arm 51 and the second connecting arm 52 pass through the installation gap 14 and are connected to the transmission rod 53. This design allows the movement of the first clamp handle 3 and the second clamp handle 4 to be transmitted to the transmission rod 53 through the first connecting arm 51 and the second connecting arm 52, ultimately controlling the opening and closing of the jaw 2. This design ensures the smoothness and accuracy of the operation. The design of the installation gap 14 provides the necessary space for the transmission assembly 5.

[0081] In one embodiment, it further includes a sleeve 15; the sleeve 15 is connected to the through-hole; the size of the sleeve 15 is adapted to the transmission assembly 5, and the transmission assembly 5 passes through the sleeve 15.

[0082] The sleeve 15 is tightly connected to the through-hole, ensuring the precise guidance of the transmission rod 53 when passing through, and avoiding deviation or shaking during operation. The inner diameter of the sleeve 15 matches the outer diameter of the transmission rod 53 (specifically, the inner diameter of the sleeve 15 matches the outer diameter of the transmission rod 53). This precise size matching helps to reduce friction during movement and at the same time protects the transmission assembly from external factors such as dust and liquid. On the premise of ensuring the smooth movement of the transmission rod 53, the sealing between the transmission rod 53 and the sleeve 15 is ensured.

[0083] In one embodiment, the transmission assembly 5 includes a first connecting arm 51, a second connecting arm 52 and a transmission rod 53. The first connecting arm 51 and the second connecting arm 52 pass through the installation gap 14. One end of the first connecting arm 51 is rotatably connected to the other end of the first pliers handle 3; one end of the second connecting arm 52 is rotatably connected to the other end of the second pliers handle 4. The other end of the first connecting arm 51 is rotatably connected to one end of the transmission rod 53 together with the other end of the second connecting arm 52; the other end of the transmission rod 53 is rotatably connected to one end of the movable jaw 22; the middle part of the movable jaw 22 is rotatably connected to the sleeve rod 1.

[0084] One end of the first connecting arm 51 is rotatably connected to the free end of the first pliers handle 3, one end of the second connecting arm 52 is rotatably connected to the free end of the second pliers handle 4, and the other end of the first connecting arm 51 and the other end of the second connecting arm 52 are both rotatably connected to one end of the transmission rod 53. Such a design allows the linear movement of the first pliers handle 3 and the second pliers handle 4 to be converted into rotational movement, ultimately controlling the opening and closing of the movable jaw 22.

[0085] The transmission rod 53 is the core of the transmission assembly 5. One end of it is connected to the first connecting arm 51 and the second connecting arm 52, and the other end is connected to the movable jaw 22. The function of the transmission rod 53 is to transmit force and convert the movement of the first pliers handle 3 and the second pliers handle 4 into the action of the jaw 2.

[0086] The middle part of the movable jaw 22 is rotatably connected to the sleeve rod 1. Specifically, the middle part of the movable jaw 22 is rotatably connected to the third sleeve rod 13. This means that the movable jaw 22 can rotate freely within the range defined by the third sleeve rod 13. Such a design allows the movable jaw 22 to open and close according to the operation of the first pliers handle 3 and the second pliers handle 4, realizing the grasping or releasing of tissues.

[0087] The design of the transmission assembly 5 ensures that the operations of the first clamping handle 3 and the second clamping handle 4 can be precisely converted into the actions of the clamping head 2, while maintaining the continuity of the suction function. Such a design not only simplifies the surgical operation but also improves the surgical efficiency and safety. By coordinating the movements of the first connecting arm 51, the second connecting arm 52, the transmission rod 53, and the movable clamping head 22, the suction grasping forceps can achieve precise grasping of tissues, and at the same time, clear the blood and smoke through the suction part to keep the surgical field of view clear.

[0088] In another embodiment, the suction part includes a suction hole 8 and a suction gap; the suction hole 8 is provided at the first end of the sleeve rod 1; the suction gap is the gap between the clamping head 2 and the sleeve rod 1.

[0089] The suction hole 8 is located at the first end of the sleeve rod 1 (i.e., the end of the third sleeve 13 away from the second sleeve rod 12), that is, the end close to the surgical site. Such a design enables the suction hole to directly face the surgical area, facilitating timely suction of the outflowing liquid.

[0090] The suction gap refers to the space between the clamping head 2 and the third sleeve 13. When the suction grasping forceps grasp tissues, the gap formed between the clamping head 2 and the first sleeve 11 will become a channel for suction of fluids.

[0091] The suction hole 8 is a plurality of through holes provided at the end of the third sleeve 13 away from the second sleeve rod 12. The plurality of through holes are distributed in multiple rows and columns, which can be a regular distribution in a matrix or an irregular distribution without disorder.

[0092] In another embodiment, it further includes an anti-slip part; the outer surfaces of the first clamping handle 3 and the second clamping handle 4 are both provided with an anti-slip part.

[0093] Specifically, the anti-slip part is a protrusion or a groove provided on the outer surfaces of the first clamping handle 3 and the second clamping handle 4.

[0094] The design of the anti-slip part is mainly to increase the holding stability of the doctor when operating the instrument, ensuring that even if the hand is contaminated with tissue fluid or other liquids during the operation, it will not easily slip off, thereby improving the safety and precision of the operation.

[0095] By providing protrusions or grooves on the outer surfaces of the first clamping handle 3 and the second clamping handle 4, the friction coefficient of the surfaces of the first clamping handle 3 and the second clamping handle 4 can be significantly increased, making it not easy for the doctor to slip when holding.

[0096] The design of the anti-slip part can improve the touch of the first clamping handle 3 and the second clamping handle 4, making the doctor feel more comfortable when operating and reducing the hand fatigue caused by long-term surgery.

[0097] Even in the case of high humidity in the surgical area or wet hands of the doctor, the anti-slip part can ensure that the doctor can firmly control the surgical forceps and avoid surgical mistakes caused by slippery hands.

[0098] Adding protrusions on the surfaces of the first forceps handle 3 and the second forceps handle 4, similar to the patterns on rubber gloves, can effectively increase the friction force.

[0099] Scratching or molding regular grooves on the surfaces of the first forceps handle 3 and the second forceps handle 4, these grooves can be longitudinally, transversely or reticularly distributed, and also play a role in increasing friction.

[0100] In the surgical environment, the doctor's hands may come into contact with blood, lubricant or other liquids. Without effective anti-slip measures, the smooth surfaces of the first forceps handle 3 and the second forceps handle 4 are likely to cause the instrument to slip, which may not only disrupt the surgical process but also cause accidental injury to the patient. Therefore, the anti-slip part is a detail that cannot be ignored in the design of the attracting grasping forceps, and it is directly related to the safety of the surgery and the doctor's operation experience.
