[0007] In some embodiments, the connecting portion includes a connecting body and an elastic element, the elastic element connecting the connecting body and the tube.

[0008] In some embodiments, the elastic element is used to hold the connection in an initial position by an elastic force; wherein the rear latch is movable between a first position and a second position, wherein the connection is in the initial position and the rear latch is between the first position and the second position.

[0009] In some embodiments, the elastic element is used to hold the tube in an initial position by elastic force; wherein, in the state where the tube is in the initial position, the end of the pliers head is separated from the shank.

[0010] In some embodiments, the tube body includes: an inner tube, sleeved outside the blade and the transmission part, and rotatably connected to the pliers head; and an outer tube, sleeved outside the inner tube, and rotatably connected to the pliers head; wherein, in a direction perpendicular to the first direction, the connection position between the pliers head and the housing body and the connection position between the pliers head and the inner tube are spaced apart, and the inner tube and the outer tube are capable of relative movement in the first direction.

[0011] In some embodiments, the inner tube is connected to the connecting portion, and the inner tube forms the transmission portion.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0024] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0025] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0026] In the following specific embodiments, the ultrasonic scalpel can be applied to any surgical scenario, such as kidney surgery or liver and gallbladder surgery. This ultrasonic scalpel allows the operator to operate it with either the left or right hand, and it can also be easily operated with the non-dominant hand. The structure of the ultrasonic scalpel and the principle of facilitating operation with the non-dominant hand are illustrated below with reference to various embodiments.

[0027] In some embodiments, combined with Figure 1 and Figure 2 The ultrasonic scalpel includes: a scalpel assembly 10, a housing 20, and a rear handle assembly 30. The scalpel assembly 10 extends along a first direction and includes a scalpel 110 and a tube 120. The tube 120 covers the tube 120 of the scalpel 110. The functional part of the scalpel assembly 10 extends outside the tube 120. This functional part can realize the surgical function of the ultrasonic scalpel through movement. For example, this part can be a forceps head with hemostasis or dissection function, or it can be a stapler capable of applying staples.

[0028] The housing 20 is detachably connected to the tool holder assembly 10. The housing 20 includes a housing body 210 and a front handle 220. The housing body 210 and the front handle 220 are fixedly connected. Optionally, the housing body 210 and the front handle 220 are integrally formed.

[0029] The rear handle assembly 30 includes a connecting part 310 and a rear handle 320, with the rear handle 320 hinged to the housing body 210. The connecting part 310 is located inside the housing body 210 and is used to connect the rear handle 320 to the tube body 120. Thus, when the rear handle 320 is driven by an external force, the movement of the rear handle 320 can drive the tube body 120 to move along a first direction. The movement of the tube body 120 can drive the functional part of the blade assembly 10 to move, thereby realizing the function required by the functional part. For example, the functional part is the cutting part at the front end of the blade 110. The tube body 120 is fixedly connected to the blade 110, so that the tube body 120 can drive the blade 110 to move linearly along the first direction, thereby enabling the cutting part to cut the patient's lesion. For example, the functional part is a stapler. The stapler is rotatably connected to the tube body. The movement of the tube body 120 along the first direction can drive the end of the stapler to move closer to or away from the blade 110, thereby enabling the stapler to fix the staples at the patient's position where hemostasis is required. The rotational motion of the rear handle 320 can be converted into the linear motion of the tube 120 in any way. For example, the tube 120 is slidably connected to the housing body 210, and the movement of the tube 120 in directions other than the first direction is restricted by the limiting effect of the housing body 210. For example, the rear handle 320 is connected to the connecting part 310 through a transmission structure. The connecting part can convert the rotational motion into linear motion, so that the rear handle 320 can drive the tube 120 to move linearly along the first direction.

[0030] Furthermore, the rear handle 320 is located on the side of the front handle 220 away from the blade shank 110. In use, the operator's forehand contacts the front handle 220, and the operator's thumb contacts the rear handle 320. The operation of the rear handle 320 is driven by the movement of the thumb. Compared with the four fingers of the forehand, the thumb has greater mobility and strength. By setting the rear handle 320 as a moving part and driving the tube body 120 to move through the rear handle 320, the ease of operation of the ultrasonic scalpel is improved.

[0031] This utility model provides an ultrasonic scalpel, which includes a shank assembly and a housing. The shank assembly extends along a first direction and includes a shank and a tube covering the shank. The housing is detachably connected to the shank assembly. The housing includes a housing body and a front handle, which are fixedly disposed. The ultrasonic scalpel also includes a rear handle assembly, which includes a connecting portion connected to the tube and a rear handle hinged to the housing body. An external force applied to the rear handle can drive the rear handle to move, causing the tube to move along the first direction. The rear handle is located at the position of the front handle. On the side away from the blade, the operator can contact the front handle with at least three fingers of the forefoot and the rear handle with the thumb. This allows the thumb to rotate the rear handle and the housing, which in turn drives the blade through the rear handle and the tube. This movement enables the ultrasonic scalpel to perform the required functions, such as opening and closing the forceps head or the stapler. Since the strength and dexterity of the thumb are much greater than those of the four forefoot fingers, moving the blade assembly of the rear handle with the thumb improves the ease of operation of the ultrasonic scalpel.

[0032] In some embodiments, such as Figure 2 As shown, the housing body 210 has a limiting portion extending along a first direction, wherein, as Figure 3 As shown, the rear handle 320 includes a rear handle body 321, a first drive part 322, and a second drive part 323. One end of the first drive part 322 is connected to the connecting part 120, and the other end of the first drive part 322 is hinged to the end of the second drive part 323. The other end of the second drive part 323 is hinged to the rear handle body 321, and the rear handle body 321 is... Figure 1The housing body 210 is hinged, that is, the rear handle body 321 is simultaneously hinged to the second drive unit 323 and the housing body 210. Moreover, at least part of the first drive unit 322 is movably disposed on the limiting part, which is used to limit the movement of the first drive unit 322 in directions other than sliding in the first direction. It can be understood that the rear handle 320 and the housing body 210 form a transmission structure. This transmission structure can convert the rotational motion of the rear handle body 321 into linear motion in the first direction, thereby driving the tube body 120 to move in the first direction. Moreover, since the transmission structure includes three moving parts and four higher kinematic pairs, the degree of freedom of the transmission structure is 1. When there is one driving part (the rear handle body 321 is the driving part), the motion of each moving part of the transmission structure is uniquely determined. Thus, the transmission structure drives the tube body 120 to always have the same displacement in the first direction when the movement angle of the rear handle body 321 is the same.

[0033] The limiting part can be any structure that can restrict the movement of the first driving part 322. For example, the limiting part can be a limiting groove extending along the first direction, and the first driving part 322 is located in the limiting groove. For example, the limiting part can also be a limiting protrusion, and the outer surface of the first driving part 322 has a limiting groove, and the limiting protrusion extends into the limiting groove.

[0034] In some embodiments, combined with Figure 4 and Figure 5 The blade assembly 10 also includes a clamp head 140, which is rotatably connected to the tube body 120. Movement of the tube body 120 along a first direction drives the clamp head 140 to rotate relative to the blade shank 110, causing the end of the clamp head 140 away from the tube body 120 to move closer to or further away from the blade shank 110. That is, the movement of the tube body 120 drives the opening and closing movement of the clamp head 140 and the blade shank 110. For example, a portion of the clamp head 140 is rotatably connected to the blade shank 110, and another portion is rotatably connected to the tube body 120, thereby enabling the movement of the tube body 120 to drive the opening and closing movement of the clamp head 140. Optionally, the end of the blade shank 110 extending out of the tube body 120 forms a cutting section 130, which enables the cutting function of the ultrasonic scalpel.

[0035] In some embodiments, combined with Figure 4 and Figure 5The tube body 120 includes an inner tube 121 and an outer tube 122. The inner tube 121 is sleeved outside the knife bar 110 and rotatably connected to the pliers head 140. The outer tube 122 is sleeved outside the inner tube 121 and is also rotatably connected to the pliers head 140. In the direction perpendicular to the first direction, the connection positions between the pliers head 140 and the outer tube 122 and between the pliers head 140 and the inner tube 121 are spaced apart. Furthermore, one of the inner tube 121 and the outer tube 122 is connected to the connecting part 310, thereby allowing one of the inner tube 121 and the outer tube 122 to... Figure 2 Driven by the rear handle 320, the pliers head 140 moves open and close relative to the knife bar 110. The pliers head 140 does not need to be rotated to the knife bar 110, making the installation and removal of the knife bar 110 and the pliers head 140 more convenient.

[0036] Optionally, the inner tube 121 is connected to the connecting part 310, and the outer tube 122 is fixedly connected to the housing body 210, so that the inner tube 121 is guided by the outer tube 122 and the pliers head 140 is driven to open and close and rotate by the inner tube 121; or the outer tube 122 is connected to the connecting part 310, and the inner tube 121 is fixedly connected to the housing body 210, so that the outer tube 122 is guided by the inner tube 121 and the pliers head 140 is driven to open and close and rotate by the outer tube 122.

[0037] In some embodiments, such as Figure 2 As shown, the connecting part 310 includes an elastic member 311, which connects the housing body 210 and the tube 120. The elastic member 311 is used to return the tube 120 to its initial position, thus eliminating the need for manual adjustment of the tube 120 and the tube body 120. Figure 4 The clamp head 140 returns to its initial position. Optionally, the elastic element 311 is a counter spring, the two ends of which are connected to the housing body 210 and the tube body 120, respectively.

[0038] In some embodiments, such as Figure 2 As shown, the elastic element 311 is used to hold the tube body 120 in its initial position by means of elastic force, wherein, when the tube body 120 is in its initial state, Figure 4 The end of the clamp head 140 is separated from the blade 110. This can be understood as follows: by applying external force to the rear handle 320 to drive the clamp head 140 and the blade 110 into a closed clamping state, hemostasis is achieved at the patient's wound. After the external force applied to the rear handle 320 is removed, the rear handle 320 and the clamp head 140 can return to their initial positions under the elastic force applied by the elastic element 311, and the clamp head 140 is in an open state. That is, the operator does not need to apply a reverse force to the rear handle 320 to manually return the clamp head 140 to the open initial position, making it easier for the operator.

[0039] In some embodiments, such as Figure 2As shown, the rear handle 320 can move between a first position and a second position. The first position and the second position are the maximum active positions that the rear handle 320 can reach under the limiting action of the limiting structure. The initial position of the rear handle 320 is located between the first position and the second position. The elastic member 311 can make the rear handle 320 return to the initial position after the external force is removed by applying an elastic force to the rear handle 320. By making the initial position between the first position and the second position, the rear handle 320 can move in two opposite directions, thereby enabling the jaws 140 to move in two opposite directions. Specifically, the jaws 140 can rotate toward the direction closer to the blade shank 110, thereby realizing the clamping function of the jaws. The jaws 140 can also rotate toward the direction away from the blade shank 110, thereby realizing the peeling function of the jaws.

[0040] In some embodiments, such as Figure 1 As shown, the housing 20 also includes an ultrasonic excitation button 270, which is used to excite the cutting section to generate ultrasonic high-frequency vibration. The ultrasonic excitation button 270 is located on the side of the front handle 220 near the blade 110. That is, the operator can operate the ultrasonic excitation button 270 with the index or middle finger to excite the blade 110 to generate ultrasonic vibration. The operator's four forefingers can be used only to operate the ultrasonic excitation button 270, and the operator's thumb can be used only to operate the rear handle 320. This allows different fingers to perform different functions independently. Compared with the technical solution that requires the use of four forefingers to perform both the handle operation and the ultrasonic excitation button operation, this reduces the flexibility requirements of the four forefingers, thereby further improving the ease of use for the operator. When the operator is operating with their non-dominant hand, the non-dominant hand can also easily use this ultrasonic scalpel.

[0041] In some embodiments, such as Figure 1 As shown, the front handle 220 includes a front handle body 221 and a tail hook 222. The handle body 221 surrounds and forms a first receiving cavity 223, which is used to receive the index finger, middle finger, and ring finger. In a direction perpendicular to the first direction, the tail hook 222 is fixed to the side of the front handle body 221 away from the housing body 210. The tail hook 222 surrounds and forms a second receiving cavity 224, which is used to receive the operator's little finger. The second receiving cavity 224 has an opening 225. In the first direction, the opening 225 is located on the side of the tail hook 222 closer to the scalpel handle 110, so that the operator's little finger can be moved out of the second receiving cavity 224 through the opening 225, reducing the restraint of the second receiving cavity 224 on the operator's little finger, thereby improving the hand comfort of the ultrasonic scalpel.

[0042] This utility model embodiment also provides a non-dominantly used bipolar ultrasonic surgical scalpel for the liver and gallbladder, such as... Figures 1 to 5 The ultrasonic scalpel shown includes a main shaft assembly, a scalpel assembly 10 including a scalpel 110 (the end of the scalpel 110 forms a cutting section), a connecting section, and a transmission section (the transmission section includes an inner tube 121 and an outer tube 122); and a housing 20, which is located on the side of the scalpel assembly near the transmission section and encloses the transmission section. The housing includes an ultrasonic scalpel housing, a rear handle assembly 30 connected to the connecting section, a transmission structure and a forceps gripping force stabilization structure device located within the housing. The gripping operation mode of the front handle 220 and the rear handle 320 improves the gripping stability during surgery. The rear handle 320 serves as the driving force to control the forceps head and the scalpel 110 to pull, separate, cut, and coagulate the tissue to be cut.

[0043] The gripping stability structure consists of an ultrasonic scalpel housing, a front grip 220 that fixes the four fingers of the forefoot, and a rear grip 320 that uses the thumb as a driving force to grip the front grip 220. The rear grip 320 is always in the zero position and automatically returns to the zero position by a return spring after activation.

[0044] Optionally, the front hand 220 is fixed to the housing by two positioning pin holes, forming a rigid connection with the housing to provide gripping space for the four fingers of the forehand. The vertical gap inside the front hand 220 is between 55 mm and 60 mm to provide space for the three fingers when gripping. The diameter of the inner circle of the finger hook structure at the tail of the front hand 220 should be between 14 mm and 16 mm to provide gripping space for the little finger.

[0045] Optionally, the rear handle assembly comprises a sliding latch, a latch pin, a connecting rod, a connecting rod pin, a rear handle pin, and a rear handle. The sliding latch and latch pin 241 are interference-fitted and engage in a groove within the ultrasonic scalpel housing, providing a limiting function. The connecting rod 250 serves as an intermediate connector between the sliding latch and the rear handle, with both ends hinged to the connecting rod pin and the latch pin, respectively, acting as a transmission component. The sliding latch forms the first driving part 322, and the connecting rod forms the second driving part 323. The rear handle assembly is hinged to the rear handle pin hole within the ultrasonic scalpel housing by the rear handle pin, allowing for counter-clockwise rotation at the illustrated position, enabling the sliding latch to move back and forth within the groove. The internal elliptical dimensions of the rear handle 320 should be between 26 mm and 28 mm in length and between 20 mm and 22 mm in width, providing driving force when engaged with the thumb.

[0046] The transmission part is divided into an inner tube 121 and an outer tube 122. The inner tube 121 and the outer tube 122 are concentrically slidingly fitted, and the connection part is located on one side of the inner tube.

[0047] Optionally, the pliers assembly has two symmetrical first connecting holes on one side, and two symmetrical hooks below the first connecting holes. The outer tube has a second connecting hole that mates with the first connecting holes. The second connecting hole and the first connecting hole are concentrically engaged by a connecting rod. The inner tube has two circular slots that mate with the hooks. The hooks move within the circular slots. When the latch is engaged, the latch assembly pulls the connecting part backward, causing the inner tube to move backward, thus allowing the pliers assembly to move towards the blade head to achieve the clamping function.

[0048] Optionally, the shape of the pliers head assembly can be matched with different pliers head assemblies depending on the shape of the cutting head.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
