Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a fixing clamp for assisting surgical cutting, and a surgical cutting assembly having the fixing clamp. Background Art

[0002] Ultrasonic Scalpel (also known as ultrasonic scalpel or ultrasonic hemostatic knife) can not only cut tissue, but also has coagulation function, and is currently widely used in surgical operations. Figure 10 As shown, an ultrasonic surgical knife generally includes a handle 100' and a blade 200'. The blade 200' is connected to the front of the handle 100'. The distal end of the blade 200' has a blade head and a clamp. When the clamp and the blade head cooperate with each other, they can clamp the part to be cut. When the transducer assembly in the handle is in operation, the blade head vibrates at a high frequency, thereby achieving cutting and sealing of blood vessels at the same time.

[0003] However, when using an ultrasonic scalpel to cut soft tissue, especially when performing surgical cutting operations on elastic tissues such as the lungs or liver, the position to be cut will shift after each cut, and the knife needs to be moved to a new position, which results in slower cutting efficiency, increased operation time and difficulty. Summary of the Invention

[0004] An object of the present invention is to provide a fixing clip for assisting surgical cutting, so as to solve one or more problems of the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a fixing clamp for assisting surgical cutting, the fixing clamp comprising two clamping arms, the two clamping arms intersecting each other and connected rotatably around a rotation centerline at the intersection, the clamping arms comprising a clamping head and a clamping handle connected along the length direction, the clamping handle being provided with a gripping portion for hand gripping and operation, the mutually opposing sides of the two clamping heads forming a clamping portion, the clamping portion and the gripping portion being respectively arranged on different sides of the rotation centerline,

[0006] Wherein, the clamping head is provided with an accommodating space capable of accommodating the distal cutting portion of the surgical cutting instrument, and the accommodating space at least has an opening facing the gripping portion.

[0007] Preferably, the clamping handle extends along a first direction, which is perpendicular to the extension direction of the rotation centerline; the clamping head extends along a second direction, which is inclined relative to the first direction.

[0008] Wherein, the opening is located on one side of the clamping handle in the thickness direction.

[0009] In some embodiments, the chuck includes a first clamping rod and a second clamping rod, and the first clamping rod and the second clamping rod are spaced apart from each other in a third direction perpendicular to the second direction, wherein the first clamping rod is connected to the clamping handle, and the accommodating space is formed between the first clamping rod and the second clamping rod.

[0010] In some embodiments, in the third direction, the two second clamping rods in the two clamping heads are located on the same side of the two first clamping rods.

[0011] In some embodiments, the first clamping rod and the second clamping rod are parallel to each other and extend along the second direction, and the chuck further includes a connecting rod connected between the first clamping rod and the second clamping rod, wherein the connecting rod is an arc-shaped rod arched away from the clamping handle along the length direction of the chuck.

[0012] In some embodiments, there is a distance w between the first clamping rod and the second clamping rod, wherein 6 mm ≤ w ≤ 10 mm.

[0013] In some embodiments, the angle between the first direction and the second direction is α, where 0<α≤45°.

[0014] In some embodiments, the angle value of α is 20°, 30°, or 45°.

[0015] In some embodiments, the clamping handle has a first side and a second side located on different sides of its thickness direction, wherein the opening is located on the first side, and the first clamping rod extends obliquely from one end of the clamping handle along the second direction toward the second side.

[0016] In some embodiments, the accommodating space has a width direction, the width direction is perpendicular to the length direction of the chuck and perpendicular to the extension direction of the rotation center line, and the accommodating space is arranged to penetrate along the width direction.

[0017] In some embodiments, the length of the fixing clip is 12 cm to 24 cm.

[0018] In some embodiments, mutually cooperating locking structures are provided on the opposite sides of the two clamping handles to limit the relative rotation of the two clamping arms around the rotation center line, wherein the locking structure includes a locking rod and a plurality of locking teeth distributed along the length direction of the locking rod, the length direction of the locking rod is perpendicular to the length direction of the clamping handle, and the two locking rods are respectively provided on the opposite sides of the two clamping handles.

[0019] The present invention also provides a surgical cutting assembly, which includes the surgical cutting auxiliary fixing clamp as described above, and a surgical cutting instrument, wherein the surgical cutting instrument has a distal cutting part located at the distal end and used for cutting operations, and the accommodating space on the fixing clamp is configured to allow the distal cutting part to be inserted therein from the opening.

[0020] In some embodiments, the surgical cutting instrument is a cutter of an ultrasonic surgical knife, wherein the length of the cutter is greater than or equal to the length of the fixing clip.

[0021] Due to the application of the above technical solution, the present invention has the following advantages: the surgical cutting auxiliary fixing clamp provided by the present invention has a chuck provided with a storage space capable of accommodating the distal cutting portion of the surgical cutting instrument.

Subsequently, the distal cutting portion of the surgical cutting instrument is extended into the storage space, and the surgical tissue in the storage space can be repeatedly cut. During this process, the surgical tissue is fixed by the chuck and does not shift. After the distal cutting portion is separated from the surgical tissue, it can be quickly repositioned to the surgical position, reducing the time for adjusting the surgical cutting instrument, thereby improving the overall cutting efficiency, shortening the operation time, and reducing the difficulty of the operation. The fixing clamp is particularly suitable for use with the blade of an ultrasonic scalpel, and is more significant in performing surgical cutting operations on elastic tissues such as the lungs or liver of the human body.

[0039] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings to make the advantages and features of the present invention more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0040] In this article, "near" and "far" are defined based on the relative distance between the surgical cutting auxiliary clamp and the operator when the operator uses the surgical cutting auxiliary clamp to perform surgical operations. Specifically, the "distal end" refers to the end away from the operator, also known as the "front end"; the "proximal end" refers to the end close to the operator, also known as the "rear end".

[0041] Figures 1 to 7 The figures are drawn in true proportion. To keep the description concise, the proportions of each component are not listed one by one. However, the proportions and positions of each component should be considered as part of the content of this description.

[0042] See also Figures 1 to 7 The shown embodiment is a fixing clamp for assisting surgical cutting, which includes two clamping arms, namely clamping arm 10 and clamping arm 20. Clamping arm 10 and clamping arm 20 intersect with each other and are connected to rotate around a rotation center line X at the intersection. Each clamping arm includes a clamping head 2 and a clamping handle 1 connected along the length direction. The clamping handle 1 is provided with a gripping portion 12 for hand gripping and operation. The opposite sides of the two clamping heads 2 form a clamping portion 2a. The clamping portion 2a and the gripping portion 12 are respectively arranged on different sides of the rotation center line X. The user grips the gripping portions 12 of the two clamping arms to drive clamping arm 10 and clamping arm 20 to rotate around the rotation center line X, which can change the angle between the two clamping heads 2, so that the fixing clamp is switched between an open state and a closed state to release or clamp the surgical tissue accordingly. In the closed state, the clamping portions 2a of the two clamping heads 2 act on the surgical tissue respectively, thereby clamping and fixing the surgical tissue.

[0043] As shown in the various figures, the retaining clamp has a receiving space S disposed on the chuck 2. The distal end of the surgical cutting instrument 30 includes a distal cutting portion 301 for cutting surgical tissue. The receiving space S is configured to accommodate the distal cutting portion 301. The receiving space S includes at least an opening h facing the grip 12, allowing the distal cutting portion 301 to enter the receiving space S through the opening h. Thus, after the retaining clamp is used to clamp surgical tissue, the surgical cutting instrument 30 can be moved from the clamp handle 1 toward the chuck 2, allowing the distal cutting portion 301 of the surgical cutting instrument 30 to enter the receiving space S through the opening h, thereby performing cutting or other surgical procedures on the surgical tissue within the receiving space S.

[0044] During the operation, after the surgical tissue is clamped with a fixing clamp, the fixing clamp can be kept in a closed state to prevent the surgical tissue from moving, and the surgical cutting instrument 30 can contact and detach from the surgical tissue multiple times to perform multiple cutting operations. During this process, since the surgical tissue is clamped by the fixing clamp and does not move, there is no need to repeatedly search for the surgical position, and it is easy to find the position. This effectively improves the efficiency of the surgical operation, reduces the surgical operation time, and correspondingly reduces the difficulty of the operation and reduces the surgical risk.

[0045] As shown in the accompanying drawings, in this embodiment, the chuck 2 is tilted relative to the handle 1. Specifically, the length of the handle 1 extends along a first direction, which is perpendicular to the extension direction of the rotation centerline X. The chuck 2 extends along a second direction, which is tilted relative to the first direction, and the opening h is located on one side of the thickness direction of the handle 1. This allows the accommodating space S on the chuck 2 to extend along the second direction, allowing the surgical cutting instrument 30 to be inserted into the accommodating space S at a predetermined angle relative to the handle 1 during surgery.

[0046] During the process of the surgical operator operating the fixing clamp and the surgical cutting instrument 30 with both hands to perform the surgical operation, such as holding the fixing clamp with the left hand to clamp and fix the surgical tissue, and holding the surgical cutting instrument 30 with the right hand to cut the surgical tissue, a certain space can be formed between the surgical cutting instrument 30 and the clamp handle 1. On the one hand, it is convenient for the surgical operator to observe the surgical site in real time through the space. On the other hand, this makes the surgical operator's body posture more comfortable during the surgical operation, and the surgical operation is more labor-saving and easy.

[0047] Specifically, see Figures 1 to 7 As shown, the chuck 2 includes a first clamping rod 21 and a second clamping rod 22. The first clamping rod 21 is connected to the clamping handle 1. Along a third direction perpendicular to the second direction, or along the thickness direction of the chuck 2, the first clamping rod 21 and the second clamping rod 22 are spaced apart from each other, and a storage space S is formed between the first clamping rod 21 and the second clamping rod 22. The first clamping rod 21 and the second clamping rod 22 are arranged in coordination as described above, so that the storage space S is set through in the width direction. It should be noted that the width direction is different from the length direction and the thickness direction of the chuck 2. It is perpendicular to the length extension direction of the chuck 2 and is also perpendicular to the extension direction of the rotation centerline X. This not only allows the surgical tissue located in the storage space S to be exposed to the outside, but also facilitates the surgical cutting instrument 30 to have sufficient room to move within the storage space S, so that it can move relative to the surgical tissue in this area to perform surgical cutting operations.

[0048] Here, the first clamping rod 21 and the second clamping rod 22 are parallel to each other and extend in the second direction. The chuck 2 also includes a connecting rod 23 connected between the first clamping rod 21 and the second clamping rod 22. The connecting rod 23 is an arc-shaped rod that arches along the length of the chuck 2 and away from the clamping handle 1. This ensures that the distal end surface of the chuck 2 is an arc-shaped surface when inserted into human tissue, which is less likely to cause damage to human tissue. At the same time, a U-shaped groove is formed between the first clamping rod 21, the connecting rod 23, and the second clamping rod 22, forming the aforementioned receiving space S with the opening h. In a specific configuration, the first clamping rod 21, the connecting rod 23, and the second clamping rod 22 are integrally formed from the same metal material to form the chuck 2.

[0049] In the fixed clamp provided in this embodiment, the two second clamping rods 22 in the two sets of clamps 2 are located on the same side of the two first clamping rods 21. Specifically, the two clamps 2 are arranged correspondingly. When the two clamps 2 are brought together, the opposing sides of the two first clamping rods 21, the two second clamping rods 22, and the two connecting rods 23 are arranged in a one-to-one correspondence. When the fixed clamp is switched to a closed state to clamp surgical tissue, the opposing sides of the two first clamping rods 21, the opposing sides of the two connecting rods 23, and the opposing sides of the two second clamping rods 22 all form clamping surfaces that contact the surgical tissue. Thus, when the fixed clamp is engaged with the surgical cutting instrument 30, the surgical tissue is clamped and fixed by the clamps 2 at all locations around the storage space S, except for the side where the surgical cutting instrument 30 needs to pass through the opening h. This ensures stable clamping and fixation of the surgical tissue, preventing it from shifting, and facilitating repeated cutting operations of the surgical cutting instrument 30 within the storage space S.

[0050] In the specific setting, the clamping handle 1 has a first side and a second side respectively arranged on two different sides of its own thickness direction, wherein the opening h of the accommodating space S is arranged on the first side, and the first clamping rod 21 extends obliquely from one end of the clamping handle 1 along the second direction toward the second side, so that the weight of the entire fixing clamp on both sides of the center plane can be basically balanced, which is conducive to reducing the fatigue of the hand when holding it for a long time.

[0051] See also Figure 7 As shown, in the fixing clamp, the angle between the first direction and the second direction is α, that is, the length extension direction of the clamp handle 1 and the length extension direction of the clamp head 2 form an angle α, and the angle value of this angle α is preferably 0<α≤45°. Specifically, the specific value of this angle α is associated with the length of the surgical cutting instrument 30 that cooperates with the fixing clamp. Specifically, when the surgical operator holds the surgical cutting instrument 30, the gripping position thereof is associated with the length value of the distal cutting portion 301. The larger the length, the smaller the angle value of α. As a preferred option, the angle α can be 20°, 30° or 45°, which can match most models of surgical cutting instruments 30 on the market.

[0052] See also Figure 7 As shown, the length of the fixing clip is 12 cm to 24 cm, specifically 12 cm, 16 cm, 20 cm, 20 cm, 24 cm, etc., which can meet the requirements for the length of the fixing clip during most types of surgical operations.

[0053] There is a distance w between the first clamping rod 21 and the second clamping rod 22, wherein 6mm≤w≤10mm, such as 6mm, 8mm or 10mm, which can allow the distal cutting portion 301 of most models of surgical cutting instruments 30 on the market to be inserted therein and perform surgical operations.

[0054] As shown in the accompanying drawings, in the fixing clamp of this embodiment, each clamp handle 1 includes a handle rod 11. A joint is formed at the distal end of the handle rod 11. Two clamping arms (clamping arm 10 and clamping arm 2 20) are rotatably connected about a rotation centerline X at this joint. The distal end of the handle rod 11 extends forward a certain distance from the above-mentioned rotational connection before connecting with the clamp head 2. A gripping portion 12 is provided at the proximal end of the handle rod 11. The gripping portion 12 has a perforation for inserting human fingers. The operator can insert different fingers of the same hand into the two gripping portions 12 to drive the two clamping arms to rotate relative to each other, thereby opening or closing the fixing clamp. In the specific configuration, the clamp head 2 and the clamp handle 1 in the same clamping arm are integrally formed from the same metal material.

[0055] The two clamping handles 1 are also provided with mutually cooperating locking structures on opposing sides to limit relative rotation of the two clamping arms about the rotational centerline X. Here, the locking structure comprises a locking rod 13 and a plurality of locking teeth 14 distributed along the length of the locking rod 13. The length of the locking rod 13 is perpendicular to the length of the clamping handles 1. The two locking rods 13 are respectively provided on opposing sides of the two clamping handles 1. Thus, when the clamp is in the closed state, the locking teeth 14 on the two locking rods 13 cooperate with each other to limit relative movement of the two clamping handles 1, thereby maintaining the clamp in the closed state and reducing the burden on the operator's hands.

[0056] like Figure 8 、 Figure 9As shown, a surgical cutting assembly formed by combining the aforementioned fixing clamp and surgical cutting instrument 30 is used. During a surgical operation, the fixing clamp clamps and secures the surgical tissue so that the surgical site to be operated on is located within the accommodation space S of the clamp head 2. The surgical cutting instrument 30 is then inserted from one side of the clamp handle 1 through the opening h of the accommodation space S into the accommodation space S, and surgical operations such as cutting are performed on the tissue located within the accommodation space S. This is particularly useful when the surgical cutting instrument 30 is a blade of an ultrasonic scalpel and / or the surgical tissue is a relatively elastic tissue such as the lung or liver, as it can significantly improve cutting efficiency, reduce surgical time, and reduce surgical difficulty.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
