Description

Technical Field

[0001] This utility model relates to the field of surgical gripper technology, specifically a non-slip laparoscopic surgical gripper with pressure feedback. Background Technology

[0002] Surgical grasping forceps are typically used by surgeons to grasp skin, tissue, or other anatomical instruments or structures during medical procedures (e.g., surgical needles and other tools such as a gentle surgical laser).

[0003] Application number CN202022298033.2 discloses a laparoscopic grasping forceps, including a forceps tube and other structures. This utility model's laparoscopic grasping forceps employs four forceps heads, and the rubber layer and grooves on the forceps heads increase friction, resulting in more stable tissue grasping and reduced pressure on blood vessels and nerves within the tissue. It can also provide electrical protection for nerves, preventing damage from electrosurgical devices. Simultaneously, it can be connected to a suction device, allowing for convenient removal of fluid from the surgical site during surgery via a switch on the handle, ensuring a clear surgical field. However, in practical use, although a suction tube is included to remove fluid from the surgical site, the tube is rigid and cannot completely remove fluid from multiple forceps head positions, resulting in some obstruction of the surgical field. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A pressure-feedback anti-slip laparoscopic surgical grasping forceps includes an instrument mechanism and a suction mechanism. The instrument mechanism includes a grasping forceps body, two pressure sensors embedded in the clamping end of the grasping forceps body, and a digital display connected to the top of the grasping forceps body. Both pressure sensors are electrically connected to the digital display. The suction mechanism includes a support frame connected to the grasping forceps body, a movable disc movably installed inside the support frame, a metal suction tube that extends laterally and movably through one end of the grasping forceps body, a rubber tube located inside the clamping end of the grasping forceps body and connected to the metal suction tube, and a guide sleeve slidably fitted onto the bottom of the metal suction tube. The guide sleeve is movably installed inside the grasping forceps body.

[0007] By adopting the above technical solution, when the rubber tube is close to the surgical site and liquid is present, the operator moves the movable plate from the round opening position. The movable plate moves the metal suction tube and rubber tube laterally or swings, allowing the rubber tube to move in the liquid. This can effectively remove the liquid from the surgical site and prevent the surgical field of vision from being obstructed.

[0008] In a preferred embodiment, the present invention can be further configured such that: the support frame is composed of a box sleeve and multiple support shafts, the multiple support shafts are arranged in a triangular pattern, the top end of the support shaft is connected to the bottom of the box sleeve, and the bottom end of the support shaft is connected to the gripper body.

[0009] In a preferred embodiment, the present invention can be further configured such that: a circular opening is provided at the top of the box sleeve, and the diameter of the circular opening is smaller than the diameter of the movable disc.

[0010] In a preferred embodiment, the present invention can be further configured such that: an opening is provided on one side of the box sleeve, and the metal straw passes through the opening laterally and movably.

[0011] In a preferred embodiment, the present invention can be further configured such that the guide sleeve consists of a rotating plate, two retaining seats and a short shaft, with the two retaining seats installed on the top of the rotating plate and the short shaft installed on the bottom of the rotating plate.

[0012] In a preferred embodiment, the present invention can be further configured such that the metal straw slides horizontally through the two card holders, and the two card holders are vertically symmetrical about the short axis.

[0013] In a preferred embodiment, the present invention can be further configured such that: the gripper body has a transverse cavity suitable for the movement of the metal suction tube, the guide sleeve is movably disposed inside the transverse cavity, and the bottom end of the short shaft extends movably to the bottom of the transverse cavity.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, when the rubber tube is close to the surgical site and liquid is present, the operator moves the movable plate from the round opening position. The movable plate moves the metal suction tube and the rubber tube laterally or swings, so that the rubber tube moves in the liquid. This can effectively suck up the liquid from the surgical site and prevent the surgical field of vision from being obstructed.

[0016] 2. In this utility model, after determining that the clamping end of the grasping forceps body is made of rubber material, the operator grasps the organ tissue at the surgical site through the grasping forceps body. Then, when the pressure sensor on the clamping end squeezes the surgical site, it displays the pressure on the clamping end on the digital display in real time, which helps the operator understand the surgical situation, control the pressure on blood vessels and nerves in the tissue, and improve the surgical effect.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a pressure feedback anti-slip laparoscopic surgical gripper.

[0030] Example 1:

[0031] Combination Figure 1-6 As shown, the present invention provides a pressure feedback anti-slip laparoscopic surgical gripper, including an instrument mechanism 100 and a suction mechanism 200. The instrument mechanism 100 includes a gripper body 110, two pressure sensors 120 embedded in the clamping end of the gripper body 110, and a digital display 130 connected to the top of the gripper body 110. Both pressure sensors 120 are electrically connected to the digital display 130.

[0032] The liquid suction mechanism 200 includes a support frame 210 connected to the gripper body 110, a movable disc 220 movably installed inside the support frame 210, a metal suction tube 230 that is transversely and movably passes through one end of the gripper body 110, a rubber tube 240 located inside the clamping end of the gripper body 110 and connected to the metal suction tube 230, and a guide sleeve 250 slidably sleeved on the bottom of the metal suction tube 230, the guide sleeve 250 being movably installed inside the gripper body 110.

[0033] Furthermore, the support frame 210 is composed of a box sleeve 211 and multiple support shafts 212 arranged in a triangular pattern. The top end of the support shaft 212 is connected to the bottom of the box sleeve 211, and the bottom end of the support shaft 212 is connected to the gripper body 110. The structural design of the support frame 210 allows it to be firmly fixed to the gripper body 110.

[0034] Furthermore, the top of the box sleeve 211 is provided with a circular opening 213. The diameter of the circular opening 213 is smaller than the diameter of the movable disk 220. The diameter design of the circular opening 213 ensures that the movable disk 220 will not separate from the box sleeve 211, thus ensuring that the movable disk 220 can move smoothly inside the box sleeve 211.

[0035] Furthermore, the box sleeve 211 has an opening 214 on one side, through which the metal straw 230 passes laterally and movably. The opening 214 provides conditions for the movement of the metal straw 230.

[0036] Example 2:

[0037] Combination Figure 3 , 5 and Figure 6 As shown, based on Embodiment 1, the guide sleeve 250 is composed of a rotating plate 251, two card holders 252 and a short shaft 253. Both card holders 252 are installed on the top of the rotating plate 251, and the short shaft 253 is installed on the bottom of the rotating plate 251. The structural design of the guide sleeve 250 can effectively limit the metal straw 230.

[0038] Furthermore, the metal straw 230 slides horizontally through the two card holders 252, and the two card holders 252 are vertically symmetrical about the short axis 253. The layout design of the card holders 252 can stably guide the metal straw 230, making the translation of the metal straw 230 more stable.

[0039] Example 3:

[0040] Combination Figure 1As shown, in the above embodiment, the gripper body 110 has a transverse cavity 300 suitable for the movement of the metal suction tube 230. The guide sleeve 250 is movably disposed inside the transverse cavity 300, and the bottom end of the short shaft 253 extends movably to the bottom of the inner cavity of the transverse cavity 300. The transverse cavity 300 is provided to give the metal suction tube 230 the conditions for flexible movement.

[0041] The working principle and usage process of this utility model are as follows: Before using this device, after confirming that the clamping end of the gripper body 110 is made of rubber, the operator uses the gripper body 110 to grasp the organ tissue at the surgical site. Then, when the pressure sensor 120 on the clamping end squeezes the surgical site, it displays the pressure on the clamping end on the digital display 130 in real time, which helps the operator understand the surgical situation and control the pressure on blood vessels and nerves in the tissue. Then, when liquid appears at the surgical site, the operator moves the movable disc 220 from the circular opening 213. The movable disc 220 moves or swings laterally with the metal suction tube 230 and the rubber tube 240. Then, the rubber tube 240 moves flexibly at the surgical site to effectively suck up the liquid at the surgical site and prevent the surgical field of vision from being obstructed.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
