Description

Technical Field

[0001] The utility model relates to the technical field of medical ultrasonic scalpels, in particular to an adjustable medical ultrasonic scalpel. Background Art

[0002] A medical ultrasonic scalpel, also known as an ultrasonic surgical knife, is a medical device that uses high-frequency ultrasonic vibrations to cut and coagulate biological tissue. Its operating principle is that the main unit outputs an electrical signal, which is converted into mechanical energy by the transducer through the electrostrictive or magnetostrictive effects, generating high-frequency vibrations. Through the amplification and coupling of the horn, the blade is driven to transmit energy to localized tissues, achieving the surgical treatment.

[0003] During thyroid surgery, surgeons use an ultrasonic scalpel to cut and coagulate tissue. The clavicle and other tissues obstruct the surgeon's surgical field of view, limiting exposure to the surgical site. This can require the surgeon to constantly adjust the angle of the scalpel with their hand to ensure accurate cutting and coagulation. To overcome this limited surgical field of view, the surgeon must constantly adjust the angle of the scalpel with their hand. This requires exceptional surgical skill and extensive clinical experience to ensure that these adjustments avoid damaging surrounding nerves, blood vessels, and organs. Furthermore, the surgeon must maintain high concentration and patience to address any potential emergencies. Furthermore, maintaining the hand in the same position for extended periods can lead to numbness and stiffness, limiting hand function. This can reduce manual dexterity and coordination and hinder the smooth progress of the surgery. Utility Model Content

[0004] The purpose of the present utility model is to provide an adjustable medical ultrasonic scalpel to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An adjustable medical ultrasonic scalpel, comprising:

[0007] A supporting body, wherein a connecting tube is fixedly provided on the supporting body, an ultrasonic blade is fixedly provided in the connecting tube, and a clamping arm is movably provided in the connecting tube;

[0008] An installation cavity, the installation cavity is provided on the supporting body, a rotating shaft is rotatably provided in the installation cavity, a worm gear is fixedly provided on the rotating shaft, and a handle 1 is fixedly provided on the rotating shaft;

[0009] A connecting plate is fixedly arranged on the supporting body, and a worm engaged with the worm wheel is rotatably arranged on the connecting plate.

[0010] Preferably, the ultrasonic blade body is connected to an ultrasonic generator, and the end of the ultrasonic blade body is provided with a blade head.

[0011] Preferably, the clamping arm extends to the supporting body through a connecting tube, a sleeve is fixedly provided on the clamping arm, and a limiting groove is provided on the sleeve.

[0012] Preferably, a connecting shaft is provided on the first handle, and a second handle is provided on the connecting shaft.

[0013] Preferably, an elastic member 1 is provided between the second handle and the first handle via a connecting sleeve.

[0014] Preferably, a sleeve 1 is provided on the handle 1, a sleeve 2 is slidably arranged on the sleeve 1, and one end of the sleeve 2 is fixedly connected to the handle 2.

[0015] Preferably, the inner cavities of the sleeve 1 and the sleeve 2 are provided with an elastic member 2.

[0016] Preferably, a pulling block is fixedly provided on the second handle, the pulling block is arranged in an arc shape, and a through groove is provided through the pulling block.

[0017] Preferably, the pulling block is slidably sleeved in the limiting groove of the sleeve through the through groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By adjusting the worm's rotation angle, the worm gear and shaft can be driven to make minute angle adjustments, thus enabling fine-tuning of the ultrasonic scalpel. This fine-tuning function allows the surgeon to more precisely control the position and angle of the ultrasonic scalpel during surgery. This fine-tuning ensures that the ultrasonic scalpel contacts the tissue at the optimal angle and position, thereby reducing surgical errors and improving surgical success rates. This provides the surgeon with greater flexibility and convenience. The surgeon can adjust the angle and position of the ultrasonic scalpel at any time according to surgical needs without interrupting the procedure or repositioning. This helps improve the surgeon's operating efficiency and comfort, reducing fatigue during surgery.

[0020] By setting the pulling block to be arc-shaped, when the rotating worm causes the worm wheel to drive the handle 1 to rotate through the rotating shaft, the pulling block rotates synchronously in the limit groove, so that when the angle of handle 1 and handle 2 is adjusted, it will not affect the linear movement of the pulling block pulling the sleeve, thereby avoiding the problem that the clamping arm cannot be closed with the cutter head when handle 1 and handle 2 are rotated. This ensures that no matter what angle the handle is at, the pulling block can smoothly pull the sleeve, thereby achieving stable closure of the clamping arm and the cutter head.

Therefore, the above terms should not be understood as limitations on the present invention.

[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0031] See also Figure 1-Figure 4 , an adjustable medical ultrasonic scalpel, comprising: a supporting body 1, which serves as the basic supporting part of the entire ultrasonic scalpel. The supporting body 1 has sufficient strength and stability to ensure that the ultrasonic scalpel body 3 and other components can be stably supported during surgery. A connecting tube 2 is fixedly provided on the supporting body 1, and an ultrasonic scalpel body 3 is fixedly provided inside the connecting tube 2. The ultrasonic scalpel body 3 is the core component for generating ultrasonic energy, and generates heat energy through high-frequency vibration for cutting and coagulating tissue. A clamping arm 5 is movably provided inside the connecting tube 2, and the clamping arm 5 is movably provided inside the connecting tube 2 for clamping and fixing the surgical site so that the ultrasonic scalpel body 3 can perform precise cutting and coagulation operations. The connecting tube 2 is fixed on the supporting body 1, and serves as a connection between the ultrasonic scalpel body 3 and the clamping arm 5 and other components;

[0032] An adjustable medical ultrasonic scalpel also includes: a mounting cavity 8, disposed on a support body 1, a rotating shaft 9 rotatably mounted within the mounting cavity 8, a worm gear 10 fixedly mounted on the rotating shaft 9, and a handle 11 fixedly mounted on the rotating shaft 9 for a doctor to hold and operate the ultrasonic scalpel; and a connecting plate 20, fixedly mounted on the support body 1, a worm 21 rotatably mounted on the connecting plate 20 for engaging with the worm gear 10. By adjusting the rotation angle of the worm gear 21, the worm gear 10 and the rotating shaft 9 can be driven to make minute angle adjustments, thereby achieving fine-tuning of the ultrasonic scalpel. This fine-tuning function allows the doctor to more precisely control the position and angle of the ultrasonic scalpel during surgery. Through fine-tuning, the doctor can ensure that the ultrasonic scalpel contacts the tissue at the optimal angle and position, thereby reducing surgical errors and improving the success rate of the operation. This provides the doctor with a more flexible and convenient operation method. The doctor can adjust the angle and position of the ultrasonic scalpel at any time according to surgical needs without interrupting the operation or repositioning. This helps improve the doctor's operating efficiency and comfort and reduces fatigue during surgery.

[0033] The ultrasonic scalpel body 3 is externally connected to an ultrasonic generator, and a blade head 4 is provided at the end of the ultrasonic scalpel body 3. The ultrasonic generator is one of the core components of the ultrasonic scalpel system. It is responsible for generating high-frequency electrical energy, converting this energy into mechanical vibration energy, and transmitting it to the ultrasonic scalpel body 3. The blade head 4 is a key component at the end of the ultrasonic scalpel body 3. It directly contacts the surgical site and performs the cutting and coagulation operations.

[0034] Furthermore, the clamping arm 5 extends to the supporting body 1 through the connecting tube 2, and a sleeve 6 is fixedly provided on the clamping arm 5, and a limiting groove 7 is provided on the sleeve 6. A connecting shaft 13 is provided on the grip 1 11, and a grip 2 12 is provided on the connecting shaft 13. An elastic member 14 is sleeved between the grip 2 12 and the grip 1 11 via the connecting shaft 13. When the doctor holds the grip 1 11 and squeezes the grip 2 12, the grip 2 12 is prompted to move linearly in the direction of the squeezing force. A sleeve 15 is provided on the grip 1 11, and a sleeve 2 16 is slid on the sleeve 15, and one end of the sleeve 2 16 is fixedly connected to the grip 2 12. An elastic member 2 17 is provided in the inner cavity of the sleeve 15 and the sleeve 2 16. By jointly setting the connecting shaft 13, the elastic member 14, the sleeve 15, the sleeve 2 16 and the elastic member 2 17, the handle 2 12 can move stably in a straight line when receiving an extrusion force. When the handle 2 12 is released, the elastic member 14 and the elastic member 2 17 lose the extrusion force and cause the handle 2 12 to return to its original state.

[0035] It should be noted that a pull block 18 is fixedly mounted on the second handle 12, and a through slot 19 is provided through the pull block 18. The pull block 18 is slidably mounted within the retaining slot 7 of the cannula 6 via the through slot 19. When the second handle 12 is squeezed, the pull block 18 pulls the cannula 6 through the retaining slot 7, thereby closing the clamping arm 5 and the cutting head 4. The surgeon can precisely adjust the degree of closure between the clamping arm 5 and the cutting head 4 by controlling the degree of squeezing of the second handle 12, thereby achieving precise control over the cutting depth and force.

[0036] It is worth mentioning that the pulling block 18 is set to be arc-shaped. When the rotating worm 21 causes the worm wheel 10 to drive the handle 11 to rotate through the rotating shaft 9, the pulling block 18 rotates synchronously in the limiting groove 7, so that the handle 11 and the handle 2 12 can be adjusted at an angle without affecting the pulling block 18 pulling the sleeve 6 to move in a straight line, thereby avoiding the problem that the clamping arm 5 cannot be closed with the cutter head 4 when the handle 11 and the handle 2 12 are rotated. This ensures that no matter what angle the handle is at, the pulling block 18 can smoothly pull the sleeve 6, thereby achieving a stable closure of the clamping arm 5 and the cutter head 4.

[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
