Description

Technical Field

[0001] This utility model relates to medical devices for laparoscopic surgery, specifically a target positioning system for gastrointestinal laparoscopic surgery. Background Technology

[0002] Laparoscopic surgery has advantages such as minimal trauma, less postoperative pain, and faster recovery, and has become the mainstream surgical method for treating digestive tract diseases such as gastric and colorectal tumors.

[0003] In laparoscopic surgery of the digestive tract, medical staff cannot directly locate the surgical target point (i.e., the location of the mass, hereinafter the same) within the abdominal cavity by touch. Therefore, it is necessary to mark and locate the surgical target point within the digestive tract through the digestive tract before or during surgery to improve surgical efficiency and avoid accidental cutting of normal tissue or conversion to open surgery. Based on this, the applicant previously disclosed a positioning clip that uses magnetism to sense the location of the surgical target point within the digestive tract from the outside. See the Chinese patent document entitled "A Target Positioning Clip for Digestive Tract Surgery," publication number CN 215384721 U, publication date January 4, 2022.

[0004] In the technology disclosed in CN 215384721 U, a magnetic structure capable of generating a magnetic field is set at the front end of the clamping arm of a Y-shaped clamp. Before surgery, the Y-shaped clamp with the magnetic structure is clamped onto the target site of the patient's digestive tract tissue through the digestive tract. During surgery, another magnetic structure performs magnetic sensing outside the digestive tract to determine the location of the surgical target. However, this technology has been found to have the following major technical problems in clinical trials:

[0005] Firstly, during the operation, another magnetic structure is needed to magnetically probe and sense the Y-shaped clip in the digestive tract. The exploration process is a relatively time-consuming process, especially when the magnetic field on the Y-shaped clip is small.

[0006] Secondly, when the magnetic field on the Y-shaped clamp is large, although it is beneficial to improve the efficiency of magnetic exploration during the operation, the large magnetic field will cause magnetic interference to the application of other metal instruments during the operation, directly affecting the flexibility and accuracy of other metal instruments during the operation.

[0007] It is evident that the technology disclosed in CN 215384721 U suffers from a technical problem where it cannot effectively balance timely magnetic detection and resistance to magnetic field interference, and requires further improvement.

[0008] The applicant has searched the publicly available related technologies and found that some technologies use visible light to locate surgical targets within the digestive tract, such as the technology published in Chinese patent literature entitled "Location Device for Preoperative Treatment of Early Endoscopic Gastrointestinal Tumors," publication number CN 209172529 U, and publication date July 30, 2019. However, such technologies involve embedding a charged light-emitting element within the digestive tract and clamping it at the surgical target location. As is well known, the power source for a charged light-emitting element is of two types: an external power source and an internal power source. An internal power source is necessarily a battery of various types. Undoubtedly, the feasibility and safety of using either an external or internal power source in clinical surgical patients are highly questionable, making it difficult to pass the ethical review required for clinical procedures, and thus hindering clinical trials and widespread application. Utility Model Content

[0009] The technical objective of this invention is to provide a safe and feasible target positioning system for gastrointestinal surgery, addressing the specific characteristics of the aforementioned laparoscopic gastrointestinal surgery and the shortcomings of existing surgical target location marking and positioning technologies. This system will not cause significant magnetic field interference to the application of other metal instruments and will be able to quickly sense the location of surgical targets within the digestive tract during surgery.

[0010] The technical objective of this utility model is achieved through the following technical solution: a target positioning system for digestive tract surgery, comprising a target clamp that can enter the patient's body through the digestive tract and clamp digestive tract tissue at the surgical target point.

[0011] The target holder has a light source that can sense electrical energy and emit light.

[0012] The target positioning system also includes a wireless power supply that provides power to the target holder wirelessly.

[0013] During gastrointestinal surgery, the target clamp holds the surgical target within the digestive tract, and the wireless power supply provides power to the target clamp from outside the digestive tract. The target clamp, sensing the power, emits a visible light signal within the digestive tract.

[0014] The aforementioned technical measures address the unique characteristics of laparoscopic gastrointestinal surgery. A target holder carrying a light source is inserted into the digestive tract, while a wireless power supply provides power to the light source from outside the digestive tract. This is achieved through electromagnetic induction between the wireless power supply and the target holder, which generates a visible light signal within the digestive tract. The target holder inside the digestive tract does not rely on batteries or wires; instead, it generates the visible light signal using electrical energy. This allows the target holder inside the digestive tract to quickly and accurately sense the surgical target location via the wireless power supply outside the digestive tract. This enables rapid and accurate marking and positioning of the surgical target. Furthermore, neither the target holder inside the digestive tract nor the wireless power supply outside the digestive tract causes significant magnetic field interference to other metal instruments. At least in clinical trials, no definitive magnetic field interference was observed. The proposed clinical trial demonstrates excellent safety and feasibility, facilitating further clinical trials and widespread application, and exhibits strong practicality. Moreover, the color of the light signal emitted by the light source on the target holder can be flexibly selected according to needs (such as the medical staff's adaptability or preference for light), which provides excellent flexibility.

[0015] As one of the preferred technical solutions, the target holder is composed of a clamp body and an electrical receiver and a light source arranged on the clamp body;

[0016] The clamp is used to hold the surgical target within the digestive tract;

[0017] The power receiver is an induction coil structure, used to sense and receive power.

[0018] The light source is electrically connected to the power receiver and is used to emit visible light signals.

[0019] The aforementioned target holder, while satisfying the clamping and positioning of digestive tract tissues, carries a light source and forms a structure that wirelessly obtains electrical energy through electromagnetic induction. It has the technical characteristics of simple structure, stable positioning, and reliable electromagnetic induction.

[0020] Furthermore, the clamp body is a Y-shaped structure composed of two clamping arms and a clamping seat that controls the closing state of the two clamping arms;

[0021] The clamp of the clamp body is used to arrange the power receiver and the light source.

[0022] The aforementioned target holder's molding structure does not hinder the function and stability of the gripper arm in holding digestive tract tissue due to the presence of a light source, nor does it hinder the function of the light source due to the presence of the gripper arm, thus exhibiting high reliability.

[0023] Furthermore, the clamping arm has an inwardly bent front end, forming an L-shaped structure capable of clamping digestive tract tissues;

[0024] The two clamping arms are arranged symmetrically at the front end of the clamping seat.

[0025] The clamp arm structure of the aforementioned target clamp ensures a stable clamping effect on the digestive tract tissues.

[0026] Furthermore, the outer contour of the clamping arm has a rounded corner structure. This technical measure makes it less likely to scratch the digestive tract tissue when clamping it, thus ensuring good safety.

[0027] Furthermore, the clamping body is made of medical-grade titanium alloy or medical-grade molded plastic. Even further, the clamping body is made of medical-grade titanium alloy. This technical measure effectively meets the safety requirements for instruments during clinical surgery and effectively complies with clinical medical standards.

[0028] As one of the preferred technical solutions, the wireless power supply consists of a housing and power transmitters arranged on the housing, and a built-in or external power supply;

[0029] The housing serves to house the power transmitter and the power source;

[0030] The power transmitter is an induction coil structure and is used to transmit electrical energy.

[0031] The power source is electrically connected to the power transmitter and is used to generate electrical energy.

[0032] The aforementioned wireless power supply has a regular and compact molding structure, which can reliably form an electromagnetic induction connection with the target holder.

[0033] Furthermore, the power supply is an external AC mains power supply;

[0034] The housing of the wireless power supply contains a miniature transformer located between the power source and the power transmitter.

[0035] The above-mentioned technical measures not only meet the technical requirements of wireless power supply, but also do not rely on batteries that pose a risk of pollution, effectively meeting the high technical requirements for hygiene and safety in operating rooms.

[0036] Furthermore, the housing of the wireless power supply has a clamping structure for clamping with forceps or for surgical personnel to hold;

[0037] The clamping structure on the housing is a raised and / or recessed anti-slip structure.

[0038] The wireless power supply of the above-mentioned technical measures facilitates clamping operations by medical staff outside the digestive tract, has good clamping stability, and is not easy to slip off.

[0039] Furthermore, the housing of the wireless power supply is made of medical-grade titanium alloy or medical-grade molded plastic. Even further, the housing of the wireless power supply is made of medical-grade titanium alloy. This technical measure effectively meets the safety requirements for instruments during clinical surgery and effectively complies with clinical medical standards.

[0040] The beneficial technical effects of this utility model are as follows: The above-mentioned technical measures address the special characteristics of the aforementioned laparoscopic surgery of the digestive tract. A target holder that can enter the digestive tract carries a light source, while a wireless power supply provides power to the light source from outside the digestive tract. Based on the electromagnetic induction between the wireless power supply and the target holder, the target holder inside the digestive tract generates a visible light signal. This allows the target holder inside the digestive tract to quickly and accurately sense the location of the surgical target by generating a visible light signal through the wireless power supply outside the digestive tract. This enables rapid and accurate marking and positioning of the surgical target. Simultaneously, neither the target holder inside the digestive tract nor the wireless power supply outside the digestive tract causes significant magnetic field interference to the application of other metal instruments. The safety and feasibility are excellent, facilitating further clinical trials and widespread application, and demonstrating strong practicality.

[0041] Compared with the technology disclosed in CN 215384721 U, the above-mentioned technical measures have the characteristics of rapid and accurate perception of the marking and positioning of surgical target points, and will not cause magnetic field interference to the application of other metal instruments. That is, it effectively balances the timeliness of exploration and the resistance to magnetic field interference, and the timeliness of exploration and the resistance to magnetic field interference are far superior to the magnetic exploration method.

[0042] Compared to the technology disclosed in CN 209172529 U, the above-mentioned technical measures do not require a power source when the target clamp is clamped and positioned in the patient's body. Instead, they rely solely on the electromagnetic induction of the wireless power supply to wirelessly obtain the necessary power. The feasibility and safety of its application in clinical surgical patients are both excellent, and it meets the ethical review requirements for clinical operations, which is conducive to conducting clinical trials and promoting its application.

[0048] This utility model relates to medical devices for laparoscopic surgery, specifically a target positioning system for gastrointestinal laparoscopic surgery. The main technical solution of this utility model is described in detail below with reference to several embodiments. Embodiment 1 is illustrated in conjunction with the accompanying drawings. Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution of this utility model is clearly and thoroughly explained; although other embodiments are not shown in separate drawings, their main structures can still be referred to the drawings of Embodiment 1.

[0049] It should be noted that the accompanying drawings of this utility model are schematic, and unnecessary details have been simplified to clarify the technical purpose of this utility model, so as to avoid obscuring the technical solution contributed by this utility model to the prior art. In addition, the expressions such as "about" and "basically" regarding quantity or fit relationship in the following text mean that reasonable assembly errors and processing errors are allowed in the industry, and do not literally describe absolute quantity or fit relationship.

[0050] Example 1

[0051] See Figure 1 and Figure 2 As shown, the target positioning system of this utility model includes a target holder 1 and a wireless power supply 2.

[0052] The target clamp 1 consists of a clamp body 13, an electrical receiver 11 (i.e., a receiving coil) arranged on the clamp body 13, and a light source 12. The clamp body 13 is used to clamp the surgical target point within the digestive tract 4, meaning the target clamp 1 can enter the patient's body through the digestive tract 4 and clamp the digestive tract tissue 3 at the surgical target point. The electrical receiver 11 is an induction coil structure used to sense and receive electrical energy through electromagnetic induction. The light source 12 is a light bulb, which is electrically connected to the electrical receiver 11. After receiving electrical energy, it is used to emit a visible light signal. The color of the visible light can be changed by replacing the corresponding light bulb as needed. Thus, the target clamp 1 has a light source 12 that can sense electrical energy and emit light.

[0053] The wireless power supply 2 consists of a housing, a power transmitter 22 (i.e., a transmitting coil) arranged on the housing, and an external power supply 21. The housing serves to house the power transmitter 22 and the power supply 21. The power transmitter 22 is an induction coil structure used to transmit electrical energy via electromagnetic induction. The power supply 21 is electrically connected to the power transmitter 22 and is used to generate electrical energy. The power supply 21 is an external mains power structure. However, since external mains power is not suitable for directly generating safe electrical energy in this invention, a miniature transformer is also arranged inside the housing of the wireless power supply 2, located between the power supply 21 and the power transmitter 22. This miniature transformer adjusts the mains power to electrical energy that conforms to electromagnetic induction and does not pose a safety risk. It can be seen that the wireless power supply 2 provides low-voltage electrical energy to the target holder 1 through electromagnetic induction wireless power supply. The wireless power supply 2 and the target holder 1 cooperate using the principle of electromagnetic induction. The transmitting coil is connected to a wired power source to generate an electromagnetic signal, and the receiving coil senses the electromagnetic signal from the transmitting end to generate a current, so that the light source 12 emits a visible light signal.

[0054] During gastrointestinal surgery, the target clamp 1 holds the surgical target within the digestive tract 4. The wireless power supply 2 provides power to the target clamp 1 from outside the digestive tract 4 (either inside or outside the abdominal cavity, usually outside the abdominal cavity for easier, more convenient, and more efficient operation). The target clamp 1, which senses the power, emits a visible light signal within the digestive tract 4, allowing medical staff to accurately perceive the location of the surgical target within the abdominal cavity.

[0055] See Figure 2 , Figure 3 and Figure 4As shown, the target clamp 1 of this utility model is a clamp body 13 formed of medical titanium alloy. The specific molding structure of the clamp body 13 is basically the same as that of conventional hemostatic titanium clamps (except for the light source 12 and power receiver 11 mentioned above). It mainly consists of two clamping arms 132 and a clamping seat 131 that controls the closing state of the two clamping arms 132. The two clamping arms 132 form a V-shaped fitting structure, and the entire clamp body 13 has a Y-shaped structure. The two clamping arms 132 are arranged symmetrically at the front end of the clamping seat 131. In the initial state, the two clamping arms 132 extend from the front end of the clamping seat 131 with a V-shaped fitting structure. When it is necessary to clamp human tissue, the two clamping arms 132 are moved backward relative to the clamping seat 131 and locked by operating the instrument. The clamping seat 131 tightens the two clamping arms 132, so that the two clamping arms 132 clamp the human tissue - namely digestive tract tissue 3. The front ends of the aforementioned two clamping arms 132 each have inwardly bent clamps, that is, the two clamping arms 132 are L-shaped structures. The L-shaped bent section of the clamping arm 132 is the clamp used to hold the front end of the digestive tract tissue 3. The end face of the clamp used to fit the digestive tract tissue is the clamping end face. The outer periphery of the clamping end face of the clamp and the outer periphery of the clamping arm are all rounded corner transition structures, that is, the outer contour of the clamping arm 132 is a rounded corner structure.

[0056] The clamp 131 of the clamp 13 is used to arrange the power receiver 11 around its circumference and to arrange the light source 12 at its front end. That is, the light source 12 is arranged on the clamp 131 at the root of the clamp arms 132 on both sides in a detachable spiral connection structure.

[0057] The housing of the aforementioned wireless power supply 2 is made of medical-grade titanium alloy. To facilitate the clamping of the wireless power supply 2 and reduce the risk of slippage during clamping, the housing of the aforementioned wireless power supply 2 has a clamping structure for clamping with clamping forceps or for surgical personnel to hold. The clamping structure on the housing is a friction-enhancing and anti-slip structure with raised and recessed molding.

[0058] Example 2

[0059] The target positioning system of this utility model includes a target holder and a wireless power supply.

[0060] The target clamp consists of a clamp body, an electrical receiver (i.e., a receiving coil) arranged on the clamp body, and a light source. The clamp body is used to hold the surgical target point within the digestive tract; that is, the target clamp can enter the patient's body through the digestive tract and clamp digestive tract tissue at the surgical target point. The electrical receiver is an induction coil structure used to sense and receive electrical energy through electromagnetic induction. The light source is a light bulb, which is electrically connected to the electrical receiver and emits a visible light signal after receiving electrical energy. Therefore, the target clamp has a light source that senses electrical energy and emits light.

[0061] The wireless power supply consists of a housing, a power transmitter (i.e., a transmitting coil) arranged on the housing, and an external power supply. The housing houses the power transmitter and the power supply. The power transmitter is an induction coil structure used to transmit electrical energy via electromagnetic induction. The power supply is electrically connected to the power transmitter and is used to generate electrical energy. The power supply is an external mains power structure. However, since external mains power cannot directly generate safe electrical energy in this invention, a miniature transformer is also arranged inside the housing of the wireless power supply, located between the power supply and the power transmitter. This miniature transformer adjusts the mains power to conform to electromagnetic induction and does not pose a safety risk. Thus, the wireless power supply provides low-voltage electrical energy to the target holder via electromagnetic induction. The wireless power supply and the target holder cooperate using the principle of electromagnetic induction. The transmitting coil, connected to a wired power supply, generates an electromagnetic signal, and the receiving coil, inducing the electromagnetic signal from the transmitting end, generates a current, causing the light source to emit a visible light signal.

[0062] During gastrointestinal surgery, a target holder clamps the surgical target within the digestive tract. A wireless power supply provides power to the target holder from outside the digestive tract (either inside or outside the abdominal cavity, but usually outside the abdominal cavity for easier, more convenient, and more efficient operation).

In the initial state, the two clamping arms extend from the front end of the clamp seat with the V-shaped engagement structure. When it is necessary to clamp human tissue, the two clamping arms are moved backward relative to the clamp seat and locked by operating the instrument. The clamp seat tightens the two clamping arms, thus clamping the human tissue—i.e., the digestive tract tissue—between the two clamping arms. The front ends of the aforementioned two clamping arms each have inwardly bent clamps, meaning that the two clamping arms are L-shaped structures. The L-shaped bent section of the clamping arm is the front end used to clamp the digestive tract tissue - the clamp. The end face of the clamp used to fit the digestive tract tissue is the clamping end face. The outer periphery of the clamping end face of the clamp and the outer periphery of the clamping arm are all rounded transition structures, meaning that the outer contour of the clamping arm is a rounded structure.

[0064] The clamps of the aforementioned clamp are used to arrange power receivers around its circumference and to arrange light sources at its front end, i.e., the light sources are arranged on the clamps at the root of the clamp arms on both sides in a fixed connection structure.

[0065] The housing of the aforementioned wireless power supply is made of medical-grade titanium alloy. To facilitate clamping of the wireless power supply and reduce the risk of slippage during clamping, the housing of the aforementioned wireless power supply has a clamping structure for clamping with forceps or for surgical personnel to hold. The clamping structure on the housing is a friction-enhancing and anti-slip structure with raised and recessed moldings.

[0066] Example 3

[0067] The target positioning system of this utility model includes a target holder and a wireless power supply.

[0068] The target clamp consists of a clamp body, an electrical receiver (i.e., a receiving coil) arranged on the clamp body, and a light source. The clamp body is used to hold the surgical target point within the digestive tract; that is, the target clamp can enter the patient's body through the digestive tract and clamp digestive tract tissue at the surgical target point. The electrical receiver is an induction coil structure used to sense and receive electrical energy through electromagnetic induction. The light source is a light bulb, which is electrically connected to the electrical receiver and emits a visible light signal after receiving electrical energy. Therefore, the target clamp has a light source that senses electrical energy and emits light.

[0069] The wireless power supply consists of a housing, a power transmitter (i.e., a transmitting coil) arranged on the housing, and an external power supply. The housing houses the power transmitter and the power supply. The power transmitter is an induction coil structure used to transmit electrical energy via electromagnetic induction. The power supply is electrically connected to the power transmitter and is used to generate electrical energy. The power supply is an external mains power structure. However, since external mains power cannot directly generate safe electrical energy in this invention, a miniature transformer is also arranged inside the housing of the wireless power supply, located between the power supply and the power transmitter. This miniature transformer adjusts the mains power to conform to electromagnetic induction and does not pose a safety risk. Thus, the wireless power supply provides low-voltage electrical energy to the target holder via electromagnetic induction. The wireless power supply and the target holder cooperate using the principle of electromagnetic induction. The transmitting coil, connected to a wired power supply, generates an electromagnetic signal, and the receiving coil, inducing the electromagnetic signal from the transmitting end, generates a current, causing the light source to emit a visible light signal.

[0070] During gastrointestinal surgery, a target holder clamps the surgical target within the digestive tract. A wireless power supply provides power to the target holder from outside the digestive tract (either inside or outside the abdominal cavity, but usually outside the abdominal cavity for easier, more convenient, and more efficient operation). The target holder, sensing the power, emits a visible light signal within the digestive tract, allowing medical staff to accurately perceive the location of the surgical target within the abdominal cavity.

[0071] The target clamp of this utility model is a medical-grade plastic molded clamp body. The specific molding structure of this clamp body is basically the same as that of a conventional hemostatic titanium clamp (except for the aforementioned light source and power receiver). It mainly consists of two clamping arms and a clamping seat that controls the closing state of the two clamping arms. The two clamping arms form a V-shaped engagement structure, and the entire clamp body has a Y-shaped structure. The two clamping arms are symmetrically arranged at the front end of the clamping seat.

[0072] The clamp of the aforementioned clamp is used to arrange power receivers around its circumference and to arrange light sources at its rear end, i.e., the light sources are arranged in a fixed structure on one end of the clamp away from the roots of the clamp arms on both sides.

[0073] The housing of the aforementioned wireless power supply is made of medical-grade plastic. To facilitate clamping of the wireless power supply and reduce the risk of slippage during clamping, the housing of the aforementioned wireless power supply has a clamping structure for clamping with forceps or for surgical personnel to hold.

[0074] Example 4

[0075] The target positioning system of this utility model includes a target holder and a wireless power supply.

[0076] The target clamp consists of a clamp body, an electrical receiver (i.e., a receiving coil) arranged on the clamp body, and a light source.

[0077] The wireless power supply consists of a housing, a power transmitter (i.e., a transmitting coil) arranged on the housing, and a built-in power supply. The housing houses the power transmitter and the power supply. The power transmitter is an induction coil structure used to transmit electrical energy via electromagnetic induction. The power supply is electrically connected to the power transmitter and is used to generate electrical energy; the power supply is a built-in battery structure. However, to meet the medical hygiene and safety requirements of the operating room, the built-in battery inside the housing should be covered with an insulating layer to prevent battery leakage. Therefore, the wireless power supply provides low-voltage electrical energy to the target holder via electromagnetic induction. The wireless power supply and the target holder work together using the principle of electromagnetic induction. The transmitting coil, connected to a wired power source, generates an electromagnetic signal, and the receiving coil, inducing the electromagnetic signal from the transmitting end, generates a current, causing the light source to emit a visible light signal.
