Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical energy cable with local elasticity and a buffer-fixed structure. Background Technology

[0002] In modern surgical procedures, such as open surgery, laparoscopic surgery, and robot-assisted surgery, doctors widely use various energy-powered instruments, including high-frequency electrosurgical units, bipolar electrocoagulation devices, ultrasonic scalpels, and radiofrequency ablation equipment. These instruments are typically connected to a main unit via cables to transmit electrical energy or energy signals. Because surgeons need to maneuver the instruments flexibly during surgery, the power cables are often designed to be sufficiently long, with some redundant segments typically placed on the operating table or near the surgical area. However, this design presents several problems: the cables on the operating table become cluttered and easily entangled with other wires, affecting the surgical process; uneven cable stress can lead to them being pulled or falling, affecting equipment stability or causing contamination. For example, patent CN207545223U discloses a multi-purpose operating room cable organizer, including an insulating fixing band one and an insulating fixing band two. One end of each insulating fixing band has an insulating fixing buckle, and the surface of the insulating fixing band has length adjustment holes that match and lock with the insulating fixing buckles. However, this patent primarily focuses on fixing and organizing cables; the cables themselves lack elasticity and buffering mechanisms, making them unsuitable for flexible use.

[0003] Therefore, there is a need for an energy cable structure that is both flexible and easy to operate, and can also locally control tension and stabilize wiring. Utility Model Content

[0004] The purpose of this invention is to provide a medical energy cable with local elasticity and a buffer-fixed structure, which is convenient and flexible to use and has stability.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] This utility model provides a medical energy cable with local elasticity and a buffer fixing structure, including a cable body. The cable body includes a host end straight segment, a partitioned elastic spiral segment, and an instrument end connecting segment connected in sequence. One end of the host end straight segment is connected to the host end, and the other end is connected to the partitioned elastic spiral segment. One end of the instrument end connecting segment is connected to the partitioned elastic spiral segment, and the other end is connected to the instrument end. The cable body is also provided with a buffer anchoring clip assembly.

[0007] More preferably, the cable body is a one-piece structure.

[0008] More preferably, the cable body includes a power conductor, and the power conductor is covered with a medical-grade flexible insulating material.

[0009] In this invention, the middle part of the cable body is set as a partitioned elastic spiral segment to provide dynamic expansion and contraction during the operation, while the main unit end connection segment and the instrument end connection segment remain in a normal straight state to ensure the stability of the equipment connection.

[0010] Preferably, the partitioned elastic helical segment includes a fine-pitch helical segment and a coarse-pitch helical segment, which are connected and transitioned by a flexible connecting segment. The fine-pitch helical segment is connected to the straight segment at the main unit end, and the coarse-pitch helical segment is connected to the connecting segment at the instrument end.

[0011] More preferably, the length of the partitioned elastic spiral segment ranges from 30 to 50 cm, which can adapt to different needs.

[0012] More preferably, the length of the straight segment at the host end ranges from 150 to 300 cm.

[0013] More preferably, the length of the instrument end connection segment ranges from 10 to 30 cm.

[0014] More preferably, the length ratio of the straight segment at the host end, the partitioned elastic spiral segment, and the connecting segment at the instrument end is 7-9:1-2:1.

[0015] Preferably, the pitch of the fine-pitch helical segment is 1-3 mm, and the pitch of the coarse-pitch helical segment is 5-8 mm.

[0016] In this invention, the partitioned elastic spiral segment is divided into two spiral structures with a flexible connection in the middle, which helps to extend and retract segmentally during surgery, improving accuracy and operational flexibility.

[0017] Preferably, a low-elongation fiber band is provided on the inner side of the partitioned elastic spiral segment along its axial direction, and the two ends of the low-elongation fiber band are respectively connected to the two ends of the partitioned elastic spiral segment.

[0018] Preferably, the low-elongation fiber tape has an elongation of 3%-8% and a breaking strength of 150-350 MPa.

[0019] In this invention, a high-strength, low-elongation fiber strip is embedded inside the partitioned elastic spiral segment and fixed to the cable at both ends. This serves two purposes: firstly, it limits the cable and controls the maximum stretching length of the elastic spiral segment; secondly, it prevents the cable from breaking or being overstretched.

[0020] Preferably, the outer surface of the partitioned elastic spiral segment is provided with transverse or oblique anti-knot texture, which can improve the surface friction of the cable and prevent the cable from rotating and knotting during the operation.

[0021] More preferably, the transverse or diagonal anti-knot texture includes a wavy, serrated, or "fishbone" texture structure.

[0022] Preferably, the buffer anchoring clip assembly is disposed at both ends of the partitioned elastic spiral segment.

[0023] More preferably, the buffer anchoring clamp assembly includes a clamp body, the clamp body includes a pair of clamp arms that are hinged to each other, the handle portion of the clamp arms is provided with a spring, and the jaw portion of the clamp arms includes a front jaw for clamping sterile drapes and a rear jaw for clamping cables.

[0024] More preferably, the front jaw is a straight jaw with a serrated structure on its inner surface.

[0025] More preferably, the rear jaw is a semi-circular groove, and a flexible pad is provided in the semi-circular groove to form a semi-circular cable groove with a flexible pad.

[0026] More preferably, the flexible pad is a silicone gasket.

[0027] More preferably, the buffer anchoring clip assembly is made of metal.

[0028] More preferably, the handle portion of the clamp arm is widened for easier gripping.

[0029] In this invention, the buffer anchoring clamp assembly is configured as a dual-function jaw. The front jaw has a parallel tooth structure for biting the sterile drape and fixing it stably. The middle section of the jaw has a semi-circular flexible padding cable groove structure for stabilizing the cable. The cable groove is lined with a silicone gasket to prevent damage to the cable.

[0030] When using this utility model, the user can attach the buffer anchoring clip assembly to the sterile drape before or during the operation, and simultaneously embed the cable into the cable groove and clamp it.

[0031] When in use, this invention allows multiple buffer anchoring clips to be used for anchoring at different positions to prevent retraction forces from interfering with instrument end operations. It can also be used for cable management after surgery.

[0032] The partitioned elastic spiral segment of this invention can automatically retract to the central area of ​​the operating table, primarily achieved through the cable's own elastic recoil capability. An anchoring clip can be installed at the end closest to the main unit (i.e., behind the elastic segment). When not in use during surgery, the elastic segment will naturally retract and stably rest at the clip, thus being centrally stored within the cable management area, effectively keeping the operating table tidy.

[0033] Preferably, the straight section of the host end is provided with a standard connection port for connecting to the host end, and the housing of the standard connection port is provided with a plug-in anti-dislodgement structure. The instrument end connection section is provided with an instrument connector for connecting to the instrument end, and the instrument connector is provided with a bayonet or rotary locking structure to prevent detachment.

[0034] More preferably, the standard connection port is suitable for mainstream energy devices, including electrosurgical units, ultrasonic scalpels, etc.

[0035] More preferably, the instrument connector is used in conjunction with devices such as an electrosurgical handle.

[0036] More preferably, the cable body is made of a high-temperature resistant material for high-temperature and high-pressure sterilization, enabling repeated use.

[0037] More preferably, the cable body is made of a lower-cost flexible material as a disposable consumable, adapting to different hospital usage scenarios and meeting different needs.

[0038] This invention provides a medical energy cable with localized elasticity and a buffered fixing structure, comprising a main unit straight segment, a partitioned elastic spiral segment, and an instrument-end connecting segment connected in sequence. This segmented structure provides localized elastic expansion and contraction within the surgical area while maintaining the stability of the main unit. Furthermore, it improves flexibility while controlling cable length, preventing excessive tangling and dragging. The partitioned elastic spiral segment is further divided into fine-pitch and coarse-pitch spiral segments, allowing for more flexible cable expansion and contraction. In addition, a buffered anchoring clip assembly is provided for cable fixation and to prevent recoil force from interfering with instrument-end operation. This buffered anchoring clip assembly combines fixation and flexibility, replacing traditional medical tape and wire channel rigid fixation methods, avoiding damage to the cable and affecting the sterile environment. It also has a certain degree of directional freedom, allowing doctors to easily adjust the cable routing direction.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] (1) This utility model adopts a segmented structure. Through the design of the main unit end straight section, the partitioned elastic spiral section, the instrument end connecting section and the buffer anchoring clip assembly, it provides a medical energy cable with local elasticity and buffer fixation structure, so as to realize the flexible arrangement of the cable and intraoperative stability.

[0041] (2) On the one hand, the present invention maintains the stability of the wiring outside the operating table by setting the straight section at the host end, and on the other hand, the doctor can freely adjust the direction and length of the cable according to the operation needs by designing the partitioned elastic spiral section, which has high flexibility.

[0042] (3) The partitioned elastic spiral segment in this utility model includes a fine-pitch spiral segment and a coarse-pitch spiral segment. The fine-pitch spiral segment is close to the main unit end, and the force transmission path is limited, which can maintain the stability of the main unit end. The coarse-pitch spiral segment is close to the instrument end, and has higher flexibility, which is convenient for doctors to operate during the operation.

[0043] (4) In this utility model, the partitioned elastic spiral segment is also provided with a low-elongation fiber strip, which is conducive to controlling the maximum stretching length of the elastic spiral segment and preventing cable breakage or excessive pulling. It will not cause continuous tension interference to the doctor's operation during the operation, thus ensuring the accuracy of the operation.

[0044] (5) In this utility model, the buffer anchoring clip assembly can achieve dynamic anchoring. The clip has the functions of non-destructive biting of the sterile drape by the front serrated jaws and adaptive clamping of the cable by the rear cable slot. It can reduce the retraction tension during the operation and prevent the cable from pulling the instrument in the opposite direction or affecting the operation accuracy. It is particularly suitable for delicate scenarios such as laparoscopic, microscopic, and robotic surgery.

[0045] (6) Compared with traditional "all-straight" or "all-flexible" cables, the segmented structure of this utility model can better control the cable direction and reduce the risk of tangling and knotting.

[0046] (7) In this utility model, the partitioned elastic spiral segment can naturally approach the center of the operating table, avoiding cables from dragging on the ground or coming into contact with contaminated areas, thus reducing the probability of contamination. At the same time, the buffer anchoring clip assembly reduces the risk of the interface being pulled off, improves equipment stability, and thus improves surgical efficiency.

[0047] (8) The cable of this utility model can directly replace the traditional energy cable and can be customized according to different equipment. It is suitable for multi-brand electrosurgical, ultrasonic, cold plasma and other energy equipment. Attached Figure Description
