技术领域Technical Field
本发明涉及手术用医疗器械技术领域，特别涉及腹腔镜辅助钳及腹腔镜手术器械。The present invention relates to the technical field of surgical medical instruments, and in particular to laparoscopic auxiliary forceps and laparoscopic surgical instruments.
背景技术Background technique
腹腔镜手术通常至少需要在患者腹部打三个孔，分别为主操作孔、辅助操作孔和摄像孔。相较开腹式手术而言，腹腔镜手术给患者的创伤较小，患者恢复快，已经成为腹腔内手术的主流方式。腹腔镜手术需要先通过穿刺器打孔后，然后将主操作手术器械、辅助手术操作器械和摄像头等通过穿刺器进入腹腔内并进行手术，腹腔镜手术打孔越多，给患者造成的痛苦也越多，还留下较多的疤痕。Laparoscopic surgery usually requires at least three holes to be made in the patient's abdomen, namely the main operation hole, the auxiliary operation hole, and the camera hole. Compared with open surgery, laparoscopic surgery causes less trauma to patients and patients recover faster, and has become the mainstream method of intra-abdominal surgery. Laparoscopic surgery requires first making a hole with a puncture, and then the main operating surgical instruments, auxiliary surgical operating instruments, and cameras are inserted into the abdominal cavity through the puncture to perform the surgery. The more holes are made in laparoscopic surgery, the more pain it causes to the patient, and more scars are left.
为此，如何在腹腔镜手术中尽量少打孔，或者打孔尽量小，成为外科医生及患者的共同心声。Therefore, how to make as few holes as possible or as small holes as possible during laparoscopic surgery has become a common concern of surgeons and patients.
有鉴于此，有必要对现有技术中的腹腔镜手术器械予以改进，以解决上述问题。In view of this, it is necessary to improve the laparoscopic surgical instruments in the prior art to solve the above problems.

实施例1Example 1
参图1至图2所示，本实施例揭示了一种腹腔镜辅助钳的一种具体实施方式。1 and 2 , this embodiment discloses a specific implementation of a laparoscopic assisted forceps.
腹腔镜辅助钳，参见图1至图2，包括手柄部1、操作杆2及操作钳头3，所述操作杆2设置锥形帽4，所述操作钳头3被束缚于锥形帽4内。The laparoscopic auxiliary forceps, referring to FIGS. 1 to 2 , comprises a handle portion 1 , an operating rod 2 and an operating forceps head 3 . The operating rod 2 is provided with a conical cap 4 , and the operating forceps head 3 is restrained in the conical cap 4 .
具体地，辅助钳通常是通过穿刺孔进入腹腔，辅助进行手术，辅助钳的外径通常也较大，需要较大的穿刺孔(0.5cm-1cm)才可以送入腹腔，为解决该问题，本实施例的辅助钳的操作杆2设置了锥形帽4，使锥形帽4的尖头部41作为穿刺直接将辅助钳送入腹腔，进入腹腔后，通过主操作钳将锥形帽4取下来，露出被束缚于锥形帽4内的操作钳头3，医生即可进行辅助手术操作。Specifically, the auxiliary forceps usually enter the abdominal cavity through the puncture hole to assist in the operation. The outer diameter of the auxiliary forceps is usually large, and a larger puncture hole (0.5cm-1cm) is required to enter the abdominal cavity. To solve this problem, the operating rod 2 of the auxiliary forceps in this embodiment is provided with a conical cap 4, so that the pointed part 41 of the conical cap 4 is used as a puncture to directly send the auxiliary forceps into the abdominal cavity. After entering the abdominal cavity, the conical cap 4 is removed by the main operating forceps to expose the operating forceps head 3 constrained in the conical cap 4, and the doctor can perform auxiliary surgical operations.
需要进一步说明的是，辅助钳的操作钳头3根据病患情况进行选择，可以是夹取钳头，也可以是钩针式钳头等。It should be further explained that the operating forceps head 3 of the auxiliary forceps is selected according to the patient's condition, and can be a clamping forceps head, a hook-type forceps head, etc.
作为优选实施例，所述尖头部41设置若干锥形楞411，设置锥形楞411有助于减小锥形帽4的穿刺阻力，另外，锥形楞411经圆滑处理后，在穿刺过程中不容易损坏肠道等。As a preferred embodiment, the pointed portion 41 is provided with a plurality of conical ridges 411. The conical ridges 411 are helpful to reduce the puncture resistance of the conical cap 4. In addition, after the conical ridges 411 are rounded, they are not easy to damage the intestines during the puncture process.
作为优选实施例，所述操作杆2外径为0.2cm-0.3cm，锥形帽4的外经略大于操作杆2的外经，能够实现辅助钳的穿刺孔孔径仅为0.2cm-0.3cm，相比传统的穿刺孔大幅减小，使患者康复更快，康复后疤痕更小。As a preferred embodiment, the outer diameter of the operating rod 2 is 0.2cm-0.3cm, and the outer diameter of the conical cap 4 is slightly larger than the outer diameter of the operating rod 2, so that the diameter of the puncture hole of the auxiliary forceps is only 0.2cm-0.3cm, which is significantly smaller than that of traditional puncture holes, allowing patients to recover faster and with smaller scars after recovery.
作为优选实施例，所述操作钳头3包括上钳头31和下钳头32，通过上钳头31和下钳头32的开合实现对患者组织的夹取。As a preferred embodiment, the operating forceps head 3 includes an upper forceps head 31 and a lower forceps head 32 , and the patient's tissue is clamped by opening and closing the upper forceps head 31 and the lower forceps head 32 .
通过上述实施例，缩小了传统辅助钳的外径尺寸，辅助钳外径小且具有穿刺功能，穿刺进入腹腔后可直接使用，给患者留下的孔洞只有0.2cm-0.3cm，相比传统的穿刺孔大幅减小，使患者康复更快，康复后疤痕更小。Through the above embodiments, the outer diameter of the traditional auxiliary forceps is reduced. The auxiliary forceps have a small outer diameter and a puncture function. They can be used directly after puncturing into the abdominal cavity. The hole left for the patient is only 0.2cm-0.3cm, which is significantly smaller than the traditional puncture hole, so that the patient can recover faster and the scar after recovery is smaller.
