Description

Endoscopic surgical devices and systems including the same

The present invention relates to an endoscopic surgical device for the treatment of diseases of organs such as the prostate, bladder, ureters, and kidneys in the field of urology. More specifically, the present invention relates to an endoscopic surgical device for the treatment of diseases of organs such as the bladder, ureters, and kidneys through minimally invasive or non-invasive surgery. It relates to an endoscopic surgical device capable of treating diseases and a system including the same.

The prostate is a male reproductive organ that surrounds the male bladder neck and posterior urethra and releases prostatic fluid. Benign prostatic hyperplasia, which is caused by the growth of prostatic adenoma, is caused by various causes such as aging and hormonal changes. It functionally blocks the passage in the lower part of the bladder where urine is discharged, causing bladder outlet obstruction, resulting in slow urine flow (slow urine flow). Stream), delayed urination, and interrupted urination.

Treatment for such benign prostatic hyperplasia is divided into pharmacological treatment such as alpha-blockers or androgen inhibitors, and surgical treatment to remove all or part of the prostate adenoma. Surgical treatments using an endoscope through the urethra include transurethral resection of prostate using electrical energy, transurethral laser vaporization of prostate, and transurethral enucleation of prostatic adenoma. .

Holmium laser enucleation of prostate (HoLEP), a representative of prostatic tumor enucleation procedures, is in the spotlight because, unlike electroprostatectomy and laser prostate vaporization, it can more completely remove enlarged prostatic adenomas from the prostatic capsule. is receiving.

The endoscopic surgery set used in endoscopic surgery is basically a combination of independent devices consisting of a telescope, an endoscope working element, and a sheath, all assembled together. Here, the operating elements of the endoscope can be changed depending on the type of surgery. Depending on the purpose of the surgery, the endoscope is replaced with a different type of operating element. For example, for electroablation, the operating element of the endoscope must accommodate a loop electrode capable of ablating or hemostasis. Through an operating element equipped with a device that allows electricity to pass through the end of the electrode, the surgeon's fingers advance and retract the annular electrode during surgery, making it possible to excise prostate tissue. In the case of holmium laser prostatoma enucleation, an operating element that can accommodate a laser fiber is used, which allows the surgeon to advance and retract the tip of the fiber to separate prostate tissue or stop bleeding.

In surgery, no single energy source can cover all surgical needs. In other words, the characteristics of each laser are different depending on the type or wavelength. A representative example of a laser with an excellent vaporization function is the KTP laser, and a laser with an excellent cutting function is the holmium laser. Electroablation methods using monopolar or bipolar electrical energy show particularly notable advantages in ablation and hemostasis. In particular, the annular electrode used in electroablation enables extensive hemostasis in a short period of time, which is incomparably superior to hemostasis using a laser. Most lasers used in surgeries in the urological field have hemostatic properties to some extent in addition to their specific functions. However, in cases where bleeding is severe, there are many blood vessels, or these findings are expected, the surgical process can be smoothened by preemptively stopping the bleeding and the surgical time can be shortened.

During a specific surgery, the detailed purpose of the surgery may change. For example, there may be cases where hemostasis is required while cutting tissue, that is, during surgery using a laser, hemostasis may be required using electrical energy. In this case, the surgery must be stopped, the endoscope disassembled, the endoscope operating elements replaced with other ones, reassembled, electricity or laser connected, and the surgery started again.

Figures 1A to 1D are diagrams showing the process of conventional holmium laser prostate tumor enucleation surgery. Referring to FIGS. 1A to 1D, the surgeon inserts the endoscope working element (20) into the patient's body through the urethra (13), and uses the laser (21) from the laser fiber accommodated in the endoscope working element (20). is examined to separate the prostatic adenoma (11) from the prostatic capsular surface (12). Thereafter, the surgeon pushes the prostate adenoma 11 separated from the prostate capsule surface 12 into the bladder 10 so that the separated prostate adenoma 11 is collected inside the bladder 10. Since the collected prostate adenoma 11 is too large to pass through the urethra 13, it is morcellated into pieces by a device such as a morcellator inside the bladder 10 and then discharged to the outside.

Meanwhile, when separating a prostate adenoma from the prostate capsule using a holmium laser, hemostasis of bleeding blood vessels must be achieved smoothly. Otherwise, the surgery cannot proceed smoothly due to bleeding, making it difficult to secure a surgical field of view. In addition, if a perforation is made in the prostate capsule on the outside of the prostatic adenoma during surgery because it is difficult to secure a surgical field of view due to bleeding, massive bleeding may occur in the large venous vessels 14 on the outside of the capsule, resulting in a very dangerous situation. You can.

Accordingly, the surgeon separates the prostate adenoma 11 from the prostate capsule surface 12 and then separates the prostate adenoma 11 from the prostate capsule surface 12 using the endoscope operating element 20 equipped with a bipolar electrode 22 for hemostasis. In many cases, an additional process of hemostasis on bleeding blood vessels must be performed. As described above, for this purpose, the surgical operator must directly reassemble the endoscope operating element 20 for hemostasis during surgery and then insert the assembled endoscope operating element 20 for hemostasis into the patient's urethra.

In addition to holmium laser prostatic tumor enucleation, a laser is used for incision and resection in laser-assisted bladder tumor resection, internal urethrotomy, bladder neck incision, and endopyelotomy. There may be cases where hemostasis is necessary. In this case, it is often necessary to additionally perform the process of hemostasis on the bleeding blood vessels on the prostate capsule surface (12) using the new endoscope operating element (20) for hemostasis after using the laser.

In this way, reassembling surgical equipment is a cumbersome process due to distractions during surgery, time delays due to temporary interruptions in surgery, and complexity in changing settings. This can not only place a burden on the surgeon who must pay close attention to the patient's anatomy and condition during surgery, but is also undesirable from the perspective of the patient undergoing the surgery. Accordingly, there is a need for endoscope operating elements that do not require reassembly of separate surgical equipment during the surgical process.

In order to solve the above problems, an embodiment of the present invention includes an endoscopic surgical device that is mechanically supplemented so that the surgical operator can focus only on the surgery without reassembling separate surgical equipment during the endoscopic surgery process. We want to provide a system that does this.
