Description

Technical Field

[0001] The present invention relates to the technical field of minimally invasive surgical tools, and more specifically, to a finger-worn surgical auxiliary tool. Background Art

[0002] Minimally invasive surgery is a branch of medical science that uses tiny trauma or tiny approaches to deliver special instruments, physical energy or chemical agents into the human body to complete surgical operations such as inactivation, removal, repair or reconstruction of lesions, deformities and traumas in the human body to achieve the purpose of treatment. Its characteristic is that the trauma to patients is significantly less than that of corresponding traditional surgical operations. Laparoscopic minimally invasive surgical scalpels are suitable for use in hospitals, reproductive centers, delivery rooms and other medical and health fields. They are used during gynecological examinations, ET (embryo transplantation) and other operations, and are mainly used for hemostasis, electrocautery separation and cutting of soft tissues. Energy generating tools such as radio frequency power supplies output energy signals to energy-carrying surgical tools such as monopolar electroscalpels, bipolar electrocoagulation forceps, electric pens, and ultrasonic scalpels, thereby generating energy such as arcs, heat energy, and mechanical vibrations to implement coagulation and tissue cutting at the contact site.

[0003] When using existing minimally invasive scalpels, medical personnel usually cut human tissue and stop bleeding by holding the electric knife installed in the pen knife. Once the pen knife is held, other tools cannot be held. Many tools are needed during the operation, and one can only put one down and then take another one or be assisted by a separate person. The operation is inconvenient. In addition, smoke is often generated when the electrocoagulation knife is used to heat human tissue. In order to avoid affecting the surgeon's vision and causing harm to the human body, the doctor or assistant is generally required to hold a special suction device to remove smoke, human tissue or blood. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a finger-worn surgical auxiliary tool, which can make the surgical tools more convenient to use and simple to replace during the operation. The special position of the sleeve ring on the finger can facilitate the operation of the tool head for surgery. Under the action of the positioning structure, the lead-out part close to the hand is not easily dragged too long or shaken too much to affect the user's surgical operation. At the same time, other tools that are not convenient to be installed on the sleeve ring can be grasped between the inner side of the user's bent finger and the palm, which increases the utilization efficiency of the user's hand during the operation and reduces the trouble of needing additional personnel to hold equipment or tools.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A finger-worn surgical auxiliary tool comprises a sleeve ring which is respectively sleeved on a plurality of fingers of a hand, a mounting seat being fixedly provided at the front end of the sleeve ring, a tool head being clamped on the mounting seat, a lead-out portion being connected to the rear end of the sleeve ring, and the lead-out portion being connected to an external power supply device, and a positioning structure for fixing the lead-out portion to the hand is sleeved on the outer wall of the rear part of the hand, so that the surgical tool can be more conveniently used and replaced by the user during the operation, and the special position setting of the sleeve ring on the finger facilitates the operation of the tool head, and under the action of the positioning structure, the lead-out portion close to the hand is not easily dragged for too long or shaken greatly to affect the user's surgical operation, and at the same time, other tools that are not convenient to be mounted on the sleeve ring can be held between the inner side of the bent finger and the palm of the user, so that the utilization efficiency of the user's hand during the operation is increased, and the trouble of needing additional personnel to hold equipment or tools is reduced.

[0009] Furthermore, the sleeve ring includes an outer sleeve ring and an inner rubber ring which are fixedly connected to each other, and the inner rubber ring is located on the inner side of the outer sleeve ring, the inner rubber ring contacts the finger, and the outer sleeve ring is sleeved at the middle part of the finger (i.e., the second joint of the finger, the cross-sectional height of the sleeve ring is less than the length of the second joint, so that when the finger is bent at a certain angle, the sleeve ring is not easy to hinder the bending of the finger), and the mounting seat is connected to the outer sleeve ring. First, because the inner rubber ring itself has a certain elasticity, when the sleeve ring is sleeved on the outside of the finger, under the action of the elastic force of the inner rubber ring, the sleeve relationship between the sleeve ring and the finger is more firmly connected. Second, the setting of the inner rubber ring can prevent the outer sleeve ring from directly and rigidly contacting the finger, thereby protecting the finger from being easily worn by the outer sleeve ring. Third, the soft material of the inner rubber ring increases the friction between the inner rubber ring and the finger, thereby preventing the sleeve ring from sliding up and down on the finger.

[0010] Furthermore, the outer sleeve connecting ring is made of insulating material, so that the charged components connected to the outer sleeve connecting ring are not likely to cause harm to the user due to leakage.

[0011] Furthermore, the outer ends of the outer sleeve ring and the inner rubber ring are provided with a plurality of mutually interconnected ventilation holes, so that when the sleeve ring is sleeved on the finger to operate the tool head for surgery, the part where the finger and the sleeve ring contact is not easily congested due to long-term airtightness, thereby improving the user's comfort during use.

[0012] Furthermore, the tool head is located on the outer sleeve ring near the outside of the finger, and the vertical distance between the tool head and the outside of the finger is 1.5-5mm. When the user bends the finger to a suitable angle, the tool head can be used for cutting without hurting the finger. The suitable distance between the tool head and the finger makes it difficult for the tool head to hinder the bending of the finger or hurt the finger during the bending process.

[0013] Furthermore, the longitudinal distance between the tool head and the bottom end of the sleeve ring is greater than the longitudinal distance between the bottom end of the finger and the bottom end of the sleeve ring. When the finger is in a straightened state, the distance between the tool head and the sleeve ring is still greater than the distance between the finger and the bottom end of the sleeve ring, thereby making it difficult for the bottom of the tool head to injure the finger during the wearing of the sleeve ring.

[0014] Furthermore, the positioning structure includes a semi-arc clamp and a plurality of limiting grooves provided on the inner wall of the semi-arc clamp, and the plurality of limiting grooves are all located near the inner top end portion of the semi-arc clamp, and the lead-out portion is fixed to the limiting groove. When the sleeve ring is put on the outside of the finger, the lead-out portion connected to the sleeve ring passes through the semi-arc clamp and then connects to the external equipment. At the same time, the lead-out portion cooperates with the corresponding limiting groove, so that when the user wears the sleeve ring for surgery, the lead-out portion is not easily dragged too long or shakes too much to affect the user's surgical operation.

[0015] Furthermore, there are four limit grooves. Because it is inconvenient to use the tool head to install the connecting ring on the thumb, the connecting ring is only installed on the remaining four fingers. The number of limit grooves is set to correspond to the number of fingers on which the connecting ring is installed, so that when the connecting ring is installed on all four fingers, the semi-arc clamping ring can limit the position of the lead-out portion on each connecting ring.

[0016] Furthermore, an elastic pad is fixedly provided on the inner wall of the semi-arc clamping ring, and the elastic pad is staggered with the position of the limiting groove. When the connecting ring is mounted on multiple fingers and the tool heads on the connecting ring are different, the diameter of the lead-out part may deviate. By setting the elastic pad, under the action of the elastic force of the elastic pad, the semi-arc clamping ring can limit the lead-out parts of multiple different diameters and fix them more firmly.

[0017] Furthermore, the tool head is any one of the electric knife, bipolar coagulation forceps, electric pen, ultrasonic knife and suction tube, so that different fingers can wear sleeve rings with different tool heads, which is convenient for switching operations during surgery. When the tool head is any one of the electric knife, bipolar coagulation forceps, electric pen and ultrasonic knife, the lead-out part is a wire, and a driving part for driving the tool head to perform corresponding procedural operations is provided in the sleeve ring. At this time, the user puts the sleeve ring on the second joint of the finger and bends the corresponding finger so that the tool head is in a vertical state, and then the subsequent corresponding procedural operations can be performed. When the tool head is a suction tube, the lead-out part is the tail of the suction tube, that is, the lead-out part is connected to an external negative pressure pump to discharge smoke, human tissue or blood generated during the surgical operation.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) This solution can make it easier for users to use surgical tools and make replacement easier during surgery. The special position of the sleeve ring on the finger makes it easier to operate the tool head for surgery. Under the action of the positioning structure, the lead-out part close to the hand is not easily dragged too long or shaken too much, which may affect the user's surgical operation. At the same time, the user can hold other tools that are not convenient to install on the sleeve ring between the inner side of the bent finger and the palm, which increases the efficiency of the user's hand utilization during surgery and reduces the need for additional personnel to hold equipment or tools.

[0021] (2) The sleeve ring includes an outer sleeve ring and an inner rubber ring which are fixedly connected to each other, and the inner rubber ring is located on the inner side of the outer sleeve ring, the inner rubber ring contacts the finger, and the outer sleeve ring is sleeved at the middle part of the finger (i.e., the second joint of the finger, the cross-sectional height of the sleeve ring is less than the length of the second joint, so that when the finger is bent at a certain angle, the sleeve ring is not likely to hinder the bending of the finger), and the mounting seat is connected to the outer sleeve ring. First, because the inner rubber ring itself has a certain elasticity, when the sleeve ring is sleeved on the outside of the finger, the sleeve relationship between the sleeve ring and the finger is more firmly connected under the elastic force of the inner rubber ring. Second, the setting of the inner rubber ring can prevent the outer sleeve ring from directly and rigidly contacting the finger, thereby protecting the finger from being worn by the outer sleeve ring. Third, the soft material of the inner rubber ring increases the friction between the inner rubber ring and the finger, thereby preventing the sleeve ring from sliding up and down on the finger.

[0022] (3) The outer sleeve connector is made of insulating material, so that the live components connected to the outer sleeve connector are not likely to cause harm to the user due to leakage.

[0023] (4) The outer ends of the outer sleeve ring and the inner rubber ring are provided with a plurality of interconnected ventilation holes, so that when the sleeve ring is put on the finger to operate the tool head for surgery, the part where the finger and the sleeve ring contact is not easily congested due to long-term airtightness, thereby improving the user's comfort during use.

[0024] (5) The tool head is located on the outer sleeve ring near the outside of the finger, and the vertical distance between the tool head and the outside of the finger is 1.5-5 mm. When the user bends the finger to a suitable angle, the tool head can be used for cutting without injuring the finger. The appropriate distance between the tool head and the finger makes it difficult for the tool head to hinder the bending of the finger or injure the finger during the bending process.

[0025] (6) The longitudinal distance between the tool head and the bottom end of the sleeve ring is greater than the longitudinal distance between the bottom end of the finger and the bottom end of the sleeve ring. When the finger is in a straightened state, the distance between the tool head and the sleeve ring is still greater than the distance between the finger and the bottom end of the sleeve ring, thereby making it difficult for the bottom of the tool head to injure the finger during the wearing of the sleeve ring.

[0026] (7) The positioning structure includes a semi-arc-shaped clamping ring and a plurality of limiting grooves formed on the inner wall of the semi-arc-shaped clamping ring. The plurality of limiting grooves are all located near the inner top end of the semi-arc-shaped clamping ring. The lead-out portion is fixed to the limiting groove. When the sleeve ring is put on the outside of the finger, the lead-out portion connected to the sleeve ring passes through the semi-arc-shaped clamping ring and then connects to the external device. At the same time, the lead-out portion cooperates with the corresponding limiting groove, so that when the user wears the sleeve ring for surgery, the lead-out portion is not easily dragged for too long or shakes too much to affect the user's surgical operation.

[0027] (8) There are four limit grooves. Since it is inconvenient to use the tool head when the connecting ring is installed on the thumb, the connecting ring is only installed on the remaining four fingers. The number of limit grooves is set to correspond to the number of fingers on which the connecting ring is installed. Therefore, when the connecting ring is installed on all four fingers, the semi-arc clamping ring can limit the position of the lead-out portion on each connecting ring.

[0028] (9) An elastic pad is fixedly arranged on the inner wall of the semi-arc clamping ring, and the position of the elastic pad is staggered with the limit groove. When the sleeve ring is sleeved on multiple fingers and the tool heads on the sleeve ring are different, the diameter of the lead-out part may deviate. By setting the elastic pad, under the elastic force of the elastic pad, the semi-arc clamping ring can limit the lead-out parts of multiple different diameters and fix them more firmly.

[0029] (10) The tool head is any one of an electrosurgical knife, a bipolar electrocoagulation forceps, an electric pen, an ultrasonic scalpel and a suction tube, so that different fingers can wear sleeve rings with different tool heads to facilitate conversion operations during surgery. When the tool head is any one of an electrosurgical knife, a bipolar electrocoagulation forceps, an electric pen and an ultrasonic scalpel, the lead-out part is a wire, and a driving part for driving the tool head to perform corresponding procedural operations is provided in the sleeve ring. At this time, the user puts the sleeve ring on the second joint of the finger and bends the corresponding finger so that the tool head is in a vertical state, and then the subsequent corresponding procedural operations can be performed. When the tool head is a suction tube, the lead-out part is the tail of the suction tube, that is, the lead-out part is connected to an external negative pressure pump to discharge smoke, human tissue or blood generated during the surgical operation.

[0040] Embodiment 1:

[0041] See also Figure 1-5 A finger-worn surgical auxiliary tool comprises sleeve rings 2 respectively sleeved on a plurality of fingers of a hand 1. After the sleeve ring 2 is sleeved on the fingers, under the action of the limiting pulling force of a lead-out portion 4, the sleeve ring 2 is not easy to slide out of the fingers at will when the fingers are in a straightened state.

[0042] See also Figure 3 The sleeve ring 2 includes an outer sleeve ring 21 and an inner rubber ring 22 which are fixedly connected to each other, and the inner rubber ring 22 is located on the inner side of the outer sleeve ring 21, and the inner rubber ring 22 contacts the finger. The outer sleeve ring 21 is sleeved at the middle part of the finger (i.e., the second joint of the finger, the cross-sectional height of the sleeve ring 2 is less than the length of the second joint, so that when the finger is bent at a certain angle, the sleeve ring 2 is not easy to hinder the bending of the finger), and the mounting seat 6 is connected to the outer sleeve ring 21. First, because the inner rubber ring 22 itself has a certain elasticity, when the sleeve ring 2 is sleeved outside the finger, under the elastic force of the inner rubber ring 22, the sleeve connection between the sleeve ring 2 and the finger is more firmly. Second, the setting of the inner rubber ring 22 can make it difficult for the outer sleeve ring 21 to directly and rigidly contact with the finger, thereby protecting the finger from being easily worn by the outer sleeve ring 21. Third, the soft material of the inner rubber ring 22 increases the friction between the inner rubber ring 22 and the finger, thereby making it difficult for the sleeve ring 2 to slide up and down on the finger.

[0043] The outer sleeve connecting ring 21 is made of insulating material, so that the live components connected to the outer sleeve connecting ring 21 are not easy to cause harm to the user due to leakage. The outer ends of the outer sleeve connecting ring 21 and the inner rubber ring 22 are opened with multiple interconnected ventilation holes 23, so that when the sleeve connecting ring 2 is put on the finger to operate the tool head 3 for surgery, the part where the finger and the sleeve connecting ring 2 contact is not easy to cause local congestion of the finger due to long-term airtightness, thereby improving the user's comfort when using it.

[0044] A mounting seat 6 is fixedly provided at the front end of the sleeve ring 2, and a tool head 3 is clamped on the mounting seat 6. The tool head 3 can be any one of an electric knife, a bipolar electrocoagulation forceps, an electric pen, an ultrasonic knife and a suction tube, so that the sleeve ring 2 with different tool heads 3 can be worn on different fingers, which is convenient for switching operations during surgery. When the tool head 3 is any one of an electric knife, a bipolar electrocoagulation forceps, an electric pen and an ultrasonic knife, the lead-out part 4 is a wire, and a driving part for driving the tool head 3 to rotate and cut is provided in the sleeve ring 2. At this time, the user puts the sleeve ring 2 on the second joint of the finger and bends the corresponding finger so that the tool head 3 is in a vertical state, and then the subsequent corresponding procedures can be performed. When the tool head 3 is a suction tube, the lead-out part 4 is the tail of the suction tube, that is, the lead-out part 4 is connected to an external negative pressure pump to discharge smoke, human tissue or blood generated during the surgical operation.

[0045] The tool head 3 is located on the outer sleeve ring 21 near the outside of the finger, and the vertical distance between the tool head 3 and the outside of the finger is 5 mm. When the user bends the finger to a suitable angle, the tool head 3 can be used for cutting without hurting the finger. The suitable distance between the tool head 3 and the finger makes it difficult for the tool head 3 to hinder the bending of the finger or hurt the finger during the bending process.

[0046] The longitudinal distance between the tool head 3 and the bottom end of the sleeve ring 2 is greater than the longitudinal distance between the bottom end of the finger and the bottom end of the sleeve ring 2. When the finger is in a straightened state, the distance between the tool head 3 and the sleeve ring 2 is still greater than the distance between the finger and the bottom end of the sleeve ring 2, so that the bottom of the tool head 3 is not easy to injure the finger during the wearing of the sleeve ring 2.

[0047] The rear end of the sleeve ring 2 is connected with a lead-out portion 4, which is connected to an external power supply device. The outer wall of the rear part of the hand 1 is sleeved with a positioning structure for fixing the lead-out portion 4 and the hand 1.

[0048] See also Figure 4The positioning structure includes a semi-arc clasp 51 and a plurality of limiting grooves 52 opened on the inner wall of the semi-arc clasp 51. The plurality of limiting grooves 52 are all located near the inner top end of the semi-arc clasp 51. The lead-out portion 4 is fixed to the limiting groove 52. When the sleeve ring 2 is sleeved outside the finger, the lead-out portion 4 connected to the sleeve ring 2 passes through the semi-arc clasp 51 and then connects to the external equipment. At the same time, the lead-out portion 4 cooperates with the corresponding limiting groove 52, so that when the user wears the sleeve ring 2 for surgery, the lead-out portion 4 close to the hand 1 is not easy to be dragged too long or shake too much to affect the user's surgical operation.

[0049] There are four limiting grooves 52. Because it is inconvenient to use the tool head 3 when the connecting ring 2 is sleeved on the thumb, the connecting ring 2 is only sleeved on the remaining four fingers. The number of 54 is set to correspond to the number of fingers on which the connecting ring 2 is sleeved, so that when the connecting ring 2 is sleeved on all four fingers, the semi-arc clamping ring 51 can limit the position of the lead-out portion 4 on each connecting ring 2.

[0050] See also Figure 5 An elastic pad 53 is fixedly arranged on the inner wall of the semi-arc clamping ring 51, and the position of the elastic pad 53 and the limiting groove 52 are staggered. When the sleeve ring 2 is sleeved on multiple fingers and the tool heads 3 on the sleeve ring 2 are different, the diameter of the lead-out portion 4 may deviate. By setting the elastic pad 53, under the elastic force of the elastic pad 53, the semi-arc clamping ring 51 can limit the lead-out portions 4 of multiple different diameters, and the fixation is relatively firm.

[0051] The device is sterilized before and after use. During use, the semi-arc clamp 51 is put on the wrist, and then the corresponding tool head 3 is clamped on the appropriate mounting seat 6 as needed, and the corresponding procedure can be performed, which is convenient for the replacement of the tool head 3. When the tool head 3 is any one of an electric knife, a bipolar electrocoagulation forceps, an electric pen and an ultrasonic knife, the lead-out part 4 is a wire, and a driving part for driving the tool head 3 to perform the corresponding procedure is provided in the sleeve ring 2. Please refer to Figure 2 At this time, the user puts the sleeve ring 2 on the second joint of the finger and bends the corresponding finger so that the tool head 3 is in a vertical state, and then the subsequent corresponding procedures can be performed. When the tool head 3 is a suction tube, the lead-out part 4 is the tail part of the suction tube, that is, the lead-out part 4 is connected to the external negative pressure pump to discharge the smoke, human tissue or blood generated during the surgical operation.

[0052] The tool head 3, the lead-out portion 4 and the driving parts that may be provided in the sleeve ring 2 are all well-known technologies to those skilled in the art. Compared with the prior art, the sleeve ring 2 in this solution replaces the pen body in the prior art. Through the arrangement of multiple sleeve rings 2, the surgical tools are more convenient to use and simple to replace during the operation. In addition, by arranging the sleeve ring 2 at a special position on the finger, it is convenient to operate the tool head 3 for surgery. Under the action of the positioning structure, the lead-out portion 4 close to the hand 1 is not easily dragged for too long or shaken too much to affect the user's surgical operation. At the same time, the user can hold other tools that are not convenient to be installed on the sleeve ring between the inner side of the bent finger and the palm, so that the utilization efficiency of the user's hand during the operation is increased, and the trouble of needing additional personnel to hold equipment or tools is reduced.

[0053] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
