Description

Disposable marking pen used under laparoscope

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a disposable marking pen used under a laparoscope.

Background

Minimally invasive techniques have been widely used in clinical fields along with the development of technologies such as electronics and optics since 90 th century, and conventional surgical operations have become a mainstream trend by minimally invasive techniques with small wounds, wherein laparoscopic techniques have been widely used in general surgical treatment, and have been increasingly emphasized due to the advantages of small technical trauma, less bleeding, rapid recovery, postoperative complications, low mortality rate, and the like.

At present, most surgical operations are finished under laparoscope, the laparoscopic operations need to make 3 1 cm wounds on the waist of a patient, corresponding lengthening surgical instruments and laparoscopes are inserted into the 3 wounds, and the operations are finished under the guidance of peripheral electronic display equipment. The endoscopic instrument is an essential tool for completing endoscopic surgery, and in addition, in surgical operations and some medical operations, a scribing pen has become an essential tool for preoperative design and intra-operative positioning marking; at present, a doctor commonly uses a common marker, or uses a tool to dip and draw a methylene blue injection for marking, or uses a special marking pen to mark, so that the information can be prevented from being distinguished; in order to accurately mark the marking pen on the human body by a doctor so as to achieve convenient operation, the marking pen has a small effect in operation, if the marking pen is required to mark organ tissues under a laparoscope, the doctor is required to clamp a cotton swab head or other methylene blue-dipped liquid to the abdominal cavity for marking off, namely medical staff is required to spend a great deal of time on marking off the part of the patient needing operation in the abdominal cavity, the working intensity of the medical staff is increased, the operation progress is delayed, the preparation time is long, the marking is inaccurate, and foreign matters are easy to leave in the abdominal cavity and the like.

Disclosure of Invention

The utility model aims to solve the defects in the prior art, and provides a disposable marking pen which can be used under a laparoscope, and according to the requirements of minimally invasive laparoscopic surgery operation, the marking pen is simplified in structure, low in cost and accurate in marking through a multi-aspect structural improvement design, can provide convenience for a clinician, reduces the difficulty of laparoscopic operation, saves disinfection time, greatly reduces risks of foreign matters leaving abdominal cavities and the like, and solves the problems.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

a disposable marking marker pen used under a laparoscope comprises a pen holder, a pen point, a pen core, a pen point and a pen cap matched with the pen point, wherein a plurality of grooves which are concave inwards for 30% of the diameter are formed in the front end of the pen holder at intervals along the circumferential direction of the outer side surface, so that the pen holder is bent in the opposite direction when being subjected to external pressure; the protruding tips formed by two adjacent grooves are arc-shaped, the pen holder is a cylinder with the diameter to length ratio of 1:30, the blue solution is filled in the pen core, one end of the pen point is exposed out of the pen point, and the other end of the pen point is connected with the pen core in the pen holder.

Further, the pen point is clamped with the front end opening of the pen holder;

further, the nib is made of a soft material resistant to high temperature and high pressure, and the tip end of the nib is in a wedge-shaped structure.

Further, the end face of the pen point, which is inserted into one end of the pen core, is an inclined plane.

Further, the pen holder comprises at least one of the following materials: synthetic rubbers, silicone rubbers, and thermoplastic elastomers.

Furthermore, the pen refill is of a columnar structure made of water absorbing materials.

Furthermore, the front end of the pen holder is bent, and the bending angle is 45-80 degrees.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the utility model, various structural improvement designs are carried out according to the operation requirement of the laparoscopic minimally invasive surgery, and a plurality of grooves which are concave inwards for 30% of the diameter are arranged at intervals along the circumferential direction of the outer side surface at the front end of the penholder, so that the penholder is bent in the opposite direction when being subjected to external pressure; because the medical staff has limited operation space under the laparoscope and is influenced by the position of the puncture outfit, if the pen used at ordinary times is straight, the medical staff is difficult to operate, the bent pen holder can enable the medical staff to more clearly see the position of the pen point, the position of the patient needing to be marked is clearly known, and the condition of inaccurate marking is avoided;

2. according to the utility model, through the arc-shaped design of the protruding tip parts formed by two adjacent grooves, the scratch of a patient when the patient is marked in the abdominal cavity is avoided;

3. the pen holder is cylindrical, and the ratio of the diameter to the length is 1:30, so that the pen holder can conveniently mark target organs or tissues from the puncture outfit to the abdominal cavity;

4. according to the utility model, the methylene blue solution is filled in the pen core, one end of the pen point is exposed out of the pen point, and the other end of the pen point is connected with the pen core in the pen holder, so that a doctor is prevented from taking a cotton swab head or other methylene blue-dipped liquid to the lower part of the abdominal cavity by using a laparoscopic instrument clamp to mark a marking mark, that is, medical staff does not need to spend a great deal of time to mark a part of the abdominal cavity of the patient to be operated, thereby reducing the working intensity of the medical staff, ensuring the operation progress, shortening the preparation time, and solving the risks of inaccurate marking, easy foreign matter left in the abdominal cavity and the like.
