Description

[Technical Field]

[0001] The present invention relates to the technical field of hemostats, and more particularly to surgical hemostats. [Background technology]

[0002] Hemostats are medical instruments used in surgery to clamp blood vessels and sever blood flow through mechanical pressure, effectively preventing intraoperative bleeding. They typically consist of a forceps head, a joint, and a handle, with a toothed lock at the end of the handle to secure the clamping position and prevent slippage. Hemostats are rigorously disinfected before use and are available in several types, including straight, curved, toothed, toothless, mosquito, and right-angle, depending on the surgical site, tissue type, and operating needs. Traditional hemostats are often made of stainless steel, which offers good corrosion resistance and mechanical strength. In recent years, research has been conducted to address issues of cleaning, rust removal, and material fracture in reusable instruments, continuously optimizing their clinical safety and durability.

[0003] Most conventional surgical hemostats currently on the market suffer from the following problems. First, the clamping mechanism is fixed, making it impossible to adjust the clamping stage specifications based on the size of different blood vessels and tissues during surgery. To accommodate different scenarios, hemostats must be replaced frequently, increasing surgical preparation time and potentially extending bleeding time during the instrument replacement process. Second, some hemostats lack clamping stability, making the clamping stage prone to slippage. This can affect hemostasis and pose a surgical risk, especially when clamping thin blood vessels. Third, the locking structure of hemostats is unreasonably designed, making them prone to loosening after locking or requiring complicated unlocking procedures, making it difficult to quickly adjust the clamping state during surgery. Summary of the Invention [Problem to be solved by the invention]

[0004] The purpose of this invention is to provide a surgical hemostat that overcomes the problems of conventional surgical hemostats. The surgical hemostat is used to clamp blood vessels and tissues to stop bleeding during surgery.

[Figure 3] 1 is a schematic plan view of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0014] In order to make the above objects, features, and advantages of the present invention more clearly comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0015] In order to more clearly explain the technical solutions of the embodiments of the present invention, the present invention will be described in detail below in conjunction with drawings and detailed embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention, and those skilled in the art can also obtain other drawings based on these drawings without paying creative labor.

[0016] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention, but the present invention may be embodied in other ways different from those described herein, and those skilled in the art will be able to make similar extensions without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

[0017] The present invention will now be described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional views of the device structure may be partially enlarged and not in accordance with a general scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of the present invention. In addition, the actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0019] This invention provides the following technical solution: during use, the surgical hemostat can be quickly replaced with a different specification of mounting rod through the detachable connection structure of the mounting groove and mounting rod, combined with the fixing action of the locking screw, depending on the size of the blood vessel or tissue during surgery, without having to replace the entire hemostat, and can meet the clamping needs in different surgical scenarios such as general surgery, orthopedics, and obstetrics and gynecology, thereby reducing the number of surgical instruments and lowering medical costs.

[0020] The inner walls of the clamping section are equipped with anti-slip stripes, which effectively increase friction with blood vessels and tissues and prevent slippage. The fixed locking block and locking post structure securely hold the clamping state of the forceps, preventing loosening during surgery, ensuring sustained and effective hemostasis and reducing surgical risks due to unstable clamping.

[0021] 1 to 3 are structural schematic diagrams of a first embodiment of the surgical hemostat of the present invention. Referring to FIGS. 1 to 3, in the surgical hemostat of this embodiment, the main body portion thereof includes a hemostat main body 100.

[0022] The hemostatic forceps body 100 includes a left forceps body 110 and a right forceps body 120. A fixed locking block 130 is attached to the left forceps body 110, and a locking post 140 is attached to the right forceps body 120. Mounting grooves 160 are attached to the ends of the left forceps body 110 and the right forceps body 120, and a mounting rod 170 is attached within the mounting groove 160. The mounting rod 170 is fixedly connected to the mounting groove 160 via a locking screw 180. A clamping portion 190 is provided on the mounting rod 170, and an anti-slip stripe 191 is provided on the inner wall of the clamping portion 190.

[0023] The hemostat body 100 includes a left forceps body 110 and a right forceps body 120, both of which are the basic support members of the hemostat. Made of medical-grade stainless steel, they have good strength and corrosion resistance, can withstand the normal clamping force during surgery, and are easy to disinfect and sterilize after surgery, meeting the requirements of medical hygiene. A fixed locking block 130 is attached to the left forceps body 110, and a corresponding locking post 140 is attached to the right forceps body 120. The fixed locking block 130 and the locking post 140 are locked together to form a locking means for the hemostatic forceps. The fixed locking block 130 has a locking groove, and when the left forceps body 110 and the right forceps body 120 are closed to clamp, the locking post 140 can be fitted into the locking groove. The engagement between the locking groove and the locking post 140 fixes the relative positions of the left forceps body 110 and the right forceps body 120, preventing the forceps body from loosening due to external force during clamping and ensuring clamping stability during the hemostatic process. When it is necessary to adjust the clamping force or release the lock, all that is required is to gently move the left and right forceps bodies 110 and 120 to release the locking posts 140 from the locking grooves, which is convenient to operate and suitable for quick adjustment during surgery.

[0024] The left and right forceps bodies 110 and 120 each have a mounting groove 160 at their ends. The mounting groove 160 has a rectangular recessed groove structure, and the size of the groove matches the mounting rod 170 to accommodate and position the mounting rod 170. The mounting rod 170 is fixedly connected to the mounting groove 160 via a locking screw 180, one end of which is threadedly connected to one side of the left and right forceps bodies 110 and 120 and passes through the mounting screw 170 to be rotatably connected to the other side of the left and right forceps bodies 110 and 120. When the mounting rod 170 needs to be installed or replaced, simply loosen the locking screw 180, insert the mounting rod 170 into the mounting groove 160, and twist the locking screw 180; the mounting rod 170 can be firmly fixed in the mounting groove 160 by the pressing force of the screw. When replacing the mounting rod 170 with a different specification, the above operation can be simply repeated, eliminating the need for complicated tools. This greatly improves the adaptability of the hemostat, allowing the mounting rod 170 with the corresponding specification to be selected according to the size of the blood vessel or tissue being operated on.

[0025] The mounting rod 170 is provided with a clamping portion 190, which is the portion that comes into direct contact with blood vessels or tissues and has anti-slip stripes 191 on its inner wall. The anti-slip stripes 191 are designed with a fine diamond pattern, thereby increasing the friction between the clamping portion 190 and blood vessels or tissues and preventing slippage during clamping. This effectively improves clamping stability, particularly when clamping thin blood vessels or smooth tissues, and prevents hemostasis failure due to blood vessel detachment.

[0026] A pivot shaft 150 is attached to the left forceps body 110, and the right forceps body 120 is connected to the left forceps body 110 via the pivot shaft 150. The pivot shaft 150 is made of a wear-resistant medical alloy material, thereby ensuring that the left forceps body 110 and the right forceps body 120 can flexibly rotate around the pivot shaft 150, allowing the forceps body to be opened and closed. The attachment position of the pivot shaft 150 is close to the center of the forceps body, which conforms to ergonomic design and allows the operator to easily control the opening and closing of the forceps body through the end of the grasping forceps body, thereby reducing the fatigue of surgical operations.

[0027] The left and right forceps bodies 110 and 120 each have a gripping ring at the end. The gripping ring has a circular ring-shaped inner diameter that fits the thickness of an adult finger, allowing the operator to easily insert their finger into the ring and control the forceps. The inner wall of the gripping ring is polished to prevent injury to the fingers during operation. The non-slip design also ensures stable control of the hemostatic forceps, improving operation accuracy even when the operator's hands are sweaty during surgery.

[0028] 1 to 3 , the specific operating principle of the surgical hemostatic forceps of this embodiment is as follows: The operator inserts his fingers into the gripping rings at the ends of the left and right forceps bodies 110 and 120, and opens and closes the forceps bodies by rotating the left and right forceps bodies 110 and 120 around the pivot shaft 150 with the opening and closing movements of his fingers. The pivot shaft 150 serves as a fulcrum, making the opening and closing process of the forceps bodies effortless and flexible. By controlling the force of the operator's fingers, the opening and closing angle of the forceps bodies can be accurately adjusted, thereby controlling the clamping range of the clamping parts 190 relative to blood vessels or tissues and adapting to clamping targets of different sizes.

[0029] When a blood vessel or tissue needs to be clamped for hemostasis, the operator closes the left and right forceps bodies 110 and 120, bringing the clamping portions 190 of the mounting rods 170 into close contact with the surface of the blood vessel or tissue. As the closing force of the forceps bodies increases, the anti-slip stripes 191 on the inner walls of the clamping portions 190 come into close contact with the blood vessel or tissue, increasing friction and preventing slippage. Furthermore, the engaging posts 140 of the right forceps body 120 gradually fit into the engaging grooves of the fixed engaging block 130 of the left forceps body 110. When the engaging posts 140 are fully engaged in the engaging grooves, the relative positions of the left and right forceps bodies 110 and 120 are fixed, the clamping force is stable, and sustained hemostasis is achieved. When it is necessary to adjust the clamping force or unlock, the operator simply moves the left and right clamp bodies 110 and 120 outward to disengage the locking posts 140 from the locking grooves, and the opening and closing angles of the clamp bodies can be readjusted, which is convenient and does not require any additional tools.

[0030] If different sizes of blood vessels or tissues need to be clamped during surgery, this can be achieved by replacing the mounting rod 170. In specific operations, the locking screw 180 is loosened. One end of the locking screw 180 is threadedly connected to one side of the forceps body, and the other end is rotatably connected to the other side of the forceps body. During the loosening process, the screw gradually releases from its crimped state on the mounting rod 170. At this time, the original mounting rod 170 is removed from the mounting groove 160 and replaced with a mounting rod 170 of the corresponding specifications (e.g., different length, different clamping diameter), which is inserted into the mounting groove 160 and the locking screw 180 is screwed in. The screw presses the mounting rod 170 to fit tightly into the mounting groove 160, completing the fixation of the mounting rod 170. This allows for quick adjustment of the clamping part 190 specifications, eliminating the need to replace the entire hemostat, thereby improving surgical efficiency.
